Calcul du taux de restitution de l'énergie potentielle G pour une section rectangulaire fissurée et comparaison avec la théorie

Abstract

The aim of this study is to calculate the restitution ratio of the potential energy G numerically for a rectangular band, which includes a central crack. The calculation is based on the Rice J integral, it is preformed using ABAQUS numerical simulation software. The obtained results are compared with the theory. Two calculations have been performed. The first by fixing the length of the crack a and varying the length L for several lengths, the second has been released by fixing the length L and varying the length of the crack a in a defined interval.
