A numerical evaluation of damage in fast dynamics

Abstract

We investigate properties of a damage model accounting for microscopic motions responsible for damage. The model evaluates structural damage, taking into account rheological and inertia effects. We investigate the properties of the effects of the more important parameters of the predictive theory in fast dynamics. They account for the inertia of the links insuring the cohesion, for local interactions at the microscopic level and for the cohesion of the material. Numerical results are obtained with the finite element method. © Springer-Verlag Berlin Heidelberg 2012.
