Nella prospettiva dominante le produzioni politiche dal basso vengono frequentemente interpretate alla luce della dicotomia efficacia/fallimento, associando ai due termini rispettivamente un valore positivo e uno negativo. Una delle... more

We present two applications of a direct one-dimensional beam model suitable for describing the buckling of thin-walled structures. The first application considers the buckling of a compressed beam with an intermediate stiffener under... more

A homogenization technique for heterogeneous elastic solids made up by a matrix containing inclusions modelled as rigid in the limit, is proposed. It is shown that the approach can cause considerable simpli®cations with respect to the use... more

In the problem of the synthesis of metamaterials, the pantographic architecture revealed remarkable potentialities. Indeed it allowed for the synthesis of second gradient 2D (nonlinear) continua: i.e. 2D shells whose deformation energy... more

A perturbation procedure for the buckling and postbuckling analysis of elastic structures is shown to be well suited to be implemented as an automatic symbolic manipulation procedure. The postbuckling analysis of a circular arch is... more

An L frame made up by beam and column having channel cross sections, has been analyzed in a previous work by two of the authors [14]. Depending on the aspect ratio and the joint configuration, it has been proved that the structure can... more

The analysis of two L-frames made up by channel sections subjected to various constraint conditions has been performed in order to determine their buckling and postbuckling behaviour. The analysis has been carried out in the framework of... more

In this paper a procedure for constructing a 1D continuum equivalent to a Koiter plate, is presented. The result is used to build-up a coarse model of a Thin Walled Beam. The model results to be a nonlinear hyperelastic 1D second gradient... more

We investigate the buckling of a ‘Roorda’ frame by means of a direct one-dimensional beam model. The frame is acted upon by a ‘dead’ load at the joint and is constrained there by an out-of-plane linear elastic spring. The possibility of... more
