Structural Integrity 2018, September 6-7, 2018, Aberdeen, UK

Structural Integrity 2019 2nd International Conference on Structural Integrity of Offshore Energy Industry, Aberdeen, September 9-10, 2019, http://asranet.co.uk/Conferences/SI2019 Structural Integrity 2019, like its predecessor Structural Integrity 2018, will be a 'boutique' conferences with some 50 papers and 100 participants, and strongly focused on its main themes. It will again bring together a 50/50 mix of international academics and industry, facilitating interactions between the two sectors. The marine, offshore and subsea energy industry continues to evolve creating new challenges and risks for the safety, integrity and reliability of its structures and systems. For example, wells are being drilled at greater depths, pressures and temperatures, requiring enhanced assessment of the integrity of structures and systems in such extreme conditions. There is a push to expand operations into new locations such as the Arctic, where environmental and operational conditions are considerably harsher. Many assets in the North Sea are rapidly reaching or have already exceeded their original design life and safe but affordable life extension and decommissioning are becoming major objectives. The recent rapid developments in renewable energy technologies have introduced new challenges of maintaining at minimum cost the reliability and integrity of structures and equipment in remote locations and subjected to extreme loads and environmental conditions. There are also exciting new opportunities, but also significant challenges and uncertainties, in applying structural health and condition monitoring and the novel concepts of additive manufacturing and big data to safety and structural integrity. These and many additional themes will be covered during the conference through survey, focused and/or case study presentations from the practitioners and researchers in the art and science of structural integrity. Keynote and invited lectures from eminent members of the structural integrity community will also be part of the program. The list of confirmed keynote and invited speakers includes prof. Kamran Nikbin (Imperial College, London), prof. Tat-Hean Gan (TWI, NSIRC and Brunel University), Dr Mark Manzocchi (Atkins), Dr Mohammed Nabavian (Wood), Dr Mark Mulheron (Surrey University), and Dr Xiaokang Yin (China University of Petroleum). Conference Themes: • Fatigue, fracture and corrosion • Deterministic deterioration models and analysis • Probabilistic deterioration models and analysis • Dealing with uncertainty in structural integrity assessment • Structural integrity under extreme loads and in extreme environments • Structural integrity of fixed, floating and submerged structures • Structural integrity of pipes and risers • Structural integrity of wind and tidal turbines and wave energy extractors • Life-cycle assessment, asset integrity management decisions and optimization • Safe and efficient asset life extension • Structural integrity in decommissioning • Reusable structures and repowering • Design for extended safe lifespan • Component and system reliability • Probabilistic computational mechanics • Multi-scale material, defect and damage modelling • Structural health and condition monitoring • Intelligent use of monitored data • ‘Digital twins’ for structural integrity • Structural integrity of additively manufactured materials • Case studies in structural integrity, safety and reliability We would also like to encourage you and your collaborators and students to submit abstracts (to [email protected]), and later papers, and attend the conference. Group discounts may be discussed for larger groups of attendees with shared affiliation. We hope to welcome you to Aberdeen in September.

HeaMES 2019 2nd International Conference on Structural Health Monitoring of Civil and Maritime Structures, https://www.asranet.co.uk/Conferences/HeaMES, May 23-24, 2019, Glasgow, UK HeaMES 2019 will be a 'boutique' conferences with some 50 papers and 100 participants, strongly centred on its focal themes. It will bring together a 50/50 mix of international academics and industry, facilitating close interactions between the two sectors. The list of confirmed keynote and invited speakers includes: - Prof. Dan Frangopol, Lehigh University, USA - Dr Daniele Inaudi, CTO, Smartec SA, Switzerland - Prof. Jung‐Ryul Lee, KAIST, Korea - Dr Abhishek Kundu, Cardiff University, UK - Prof. Franklin Moon, Rutgers University, USA - Prof. Carlo Rainieri, University of Molise, Italy - Prof. Franck Schoefs, University of Nantes, France - Prof. S. A. Sudath Siriwardane, University of Stavanger, Norway - Dr Helder Sousa, HS Consul􀆟ng, Portugal - Dr Abishek Kundu, Cardiff University, UK - Prof. Tomonori Nagayama, University of Tokyo, Japan - Prof. Jung-Ryul Lee, KAIST, Korea - Dr Irina Trendafilova, Strathclyde University, UK - Prof. Lars Damkilde, Aalborg University, Denmark - Prof. Monssef Drissi-Habti, Consortium Durability of Smart Structures, France - Dr Ales Znidaric, Slovenian National Building & Civil Engineering Institute - Prof. Eleni Chatzi, ETH Zurich, Switzerland - Prof. Iris Tien, Georgia Institute of Technology, USA - Dr Sylvain Chatainger, IFSTTAR, France - Dr Phil Cole, Mistras There is an urgent need for further progress in structural health monitoring for both civil and maritime structures. Maximising the availability and productivity of onshore and offshore infrastructure and marine vessels, whilst operating them safely and with minimal impact on the environment, is of major concern to operators. Many such structures are unique, e.g. ships such as FPSOs have specific constraints, loading characteristics and damage consequences that make them different to other offshore installations and conventional ships, and often more challenging to maintain and operate. Market research shows that there is a need for efficient SHM which could facilitate structural, fatigue and corrosion analyses and underpin risk-based inspections to address the structural integrity of onshore and offshore structures. Radical developments in the telecommunication, sensor and data processing technologies are transforming the way that asset management is conceived and carried out. Sensors and structural health monitoring systems are increasingly becoming an integral part of new and existing buildings, bridges, offshore structures and installations, and vessels. Sensing arrays can be permanently connected to distributed management networks so that owners, users, and in general, all those involved in the management process - connected via the Internet - can query in real time condition and performance during construction and operation. Whereas today the structural engineer conceives the single building or bridge as a stand-alone project, in future it is likely that structures will be regarded as nodes of a complex infrastructure network. Design specifications, real-time operation, and any decision on maintenance, upgrading and reconstruction of the single node will reflect the management policy of the whole system, properly accounting for concepts such as cost, risk and sustainability and structural health monitoring will play a critical role in these transformed approaches. HeaMES 2019 provides an ideal platform for innovative industry and practitioners, leading researchers, technology developers, and supply chain partners to meet. Bringing the pioneering experts together, the conference aims to promote exchange of ideas, recent research and ways forward to application and commercialisation. Conference Themes: • Performance and condition monitoring • Quantitative SHM-based reliability, safety and performance assessment • Modelling and dealing with uncertainty in SHM data • Economic analysis of SHM strategies and benefits • Management of structures exceeding design life • Damage control, repair and strengthening • Damage detection • Modelling of operational and environmental influences • Digital twin/SHM integration • SHM-based design • Validation and certification • Design guidelines and codes • Signal processing • Big data in SHM • Real time monitoring • Standardization of SHM systems • Sensors and actuators for infrastructure instrumentation • Sensor networks • Remote monitoring systems • Global system integration • Smart structures and materials • Field applications and case studies • Critical issues in SHM • Visionary, disruptive and transformational concepts We would also like to invite and encourage you and your collaborators and students to submit abstracts (to [email protected] by 23nd Nov 2018), and later papers, and attend the conference.

1997

A structure or a component is expected to perform specific functions for a minimum specified period of time. If it ceases to do so, it is said to have failed. The consequence of service failure can be tragic and expensive. There are innumerable cases of engineering disasters resulting in loss of life and property. Therefore, utmost care and attention are required to be given to critical structures / components to ensure that such incidents do not take place. Integrity evaluation performed at regular intervals is a means to ensure absence of such tragic service failure. It also gives us an estimate of its remaining life which is essential to plan future course of action so that it could be used till the very end of its real life. Recent development of powerful non-destructive techniques and availability of modern computational facility at affordable cost has made this a routine exercise for many critical applications. This paper describes the basic principles behind structural and co...

International Journal of Fracture

This themed issue is dedicated to highlighting scientific issues associated with the design, safety, reliability, and integrity of materials and structural components. The special collection is focused on issues related to structural integrity, durability, safety, probabilistic approaches, mathematical problems, loading effects, fatigue, fracture mechanics, damage mechanics, analytical and numerical simulation, experimental observations, and other related areas. The manuscripts of this themed issue are from engineers, metallurgists, and structural scientists, among others, that allowed a very multidisciplinary discussion. Twenty scientific papers, including three review papers are published in this special volume. Zakavi et al. (2021a) presented a brief overview of three-dimensional linear-elastic fracture mechanics (3D LEFM). In this review, the classical linear elastic fracture mechanics (LEFM), which largely relies on plane stress or plane strain simplifications, is approached and discussed. Additionally, the fundamental results in 3D LEFM, which are largely based on dimensionless and energy considerations, are also reviewed and discussed. Zhu et al. (2021) presented a review of the recent advances on the size effect in metal fatigue under defects. Three types of size effects (statistical, geometrical, technological) as well as their recent advances in metal fatigue, aiming to provide a guide for fatigue strength assessment of engineering

Strength, Fracture and Complexity

The International Congress on Fracture (ICF) was created through the vision of Takeo Yokobori in Sendai, Japan in 1965. The primary emphasis of Yokobori was to join the micro-and macro-mechanics aspects of fracture research. The outstanding growth of ICF demonstrates that the founding effort was the right approach to the right topic at the right time. The "ICF Brand" is now recognised around the world as one of the leading international societies in the broad field of structural integrity, fracture, fatigue, creep, corrosion and reliability-from biological to geophysical materials, from nano to macro scales, from basic science to practical engineering and technology and systems modelling. In this paper we trace the history of the development of fracture research and of ICF via the many threads of, for example, the E24/E9 committees of ASTM; the US Committee on Ship Steel linked to work on the Liberty Ships in the Engineering Laboratories, Cambridge, England; early work in Germany, France and Japan-culminating in the MIT Swampscott Fracture Conference of 1959 ("ICF0"), the precursor to ICF1 in Sendai in 1965. We then examine the impact of the ICF quadrennial series of international fracture conferences from ICF1 through to ICF12 in Ottawa, Canada in 2009. The key is the original research presented in some 5000 scientific papers and to be made available online on the new ICF website (www.icf-wasi.org). Finally we examine the evolution of ICF since 2009 towards ICF13 in Beijing, China in 2013 (www.ICF13.org) and forward for the next decade and beyond.

Despite all the advice and guidance and the increasingly sophisticated methods of analyses available in recent years, failure of structures still occur. While these failures can be the result of the structure being exposed to extreme events, greater than the structure was designed to withstand (say due to global warming), failure is mainly because of deficiencies in their design or their construction. Such failures are, however, rarely due to a single ‘error’, but can be the combination of, say, an inappropriate aspect of the design, lack of quality control during construction or of construction methods or of taking the present levels of knowledge beyond its limits.
