A study of the behavior under shear of existing wooden floors reinforced with different materials and techniques has been carried out. The purpose of this study was to perform an experimental and numerical analysis of the shear properties... more
A simple model for history dependent nonlinear viscoelasticity is considered. The determining equation governing shear motions is derived and investigated in the quasistatic approximation and under the traveling waves ansatz. Traveling... more

This paper is devoted to a discussion of the reduction methods for evolution equations based on invariant surface conditions related to functional separation of variables. The relationship of these methods with nonclassical and weak point... more

We show that finite-amplitude shearing motions superimposed on an 'unsteady' simple extension are admissible for incompressible isotropic viscoelastic materials of differential kind. The amplitude of these motions is determined by solving... more
In this paper, following the lines of a Noether's theorem, is established the complete set of generators of conservation laws related to geometric symmetries for linear theory of isotropic micropolar elastostatic.
We consider nonlinear viscoelastic materials of differential type and for some special models we derive exact solutions of initial boundary value problems. These exact solutions are used to investigate the reasons for the non-existence of... more
We present the results of a systematical investigation of invariance properties of a semilinear hyperbolic equation u,, = J(u), under a one-parameter Lie group of transformations, for arbitrary f(u). The intinitesimais, resulting... more
