Recent Trends in the Development of Gurson’s Model

What is it about?

The original Gurson model for porous materials has undergone numerous modifications in order to improve its adequacy with experimental or numerical results. In this chapter various modifications of Gurson’s model and models created on the basis of the idea of Gurson’s model are presented. This chapter includes the following issues: (i) development of Gurson’s model, (ii) development of models for nucleation, growth and coalescence of voids and (iii) modification of Gurson’s model for failure prediction under shear deformation.

Why is it important?

The modified Gurson model is a degradation model for ductile materials, which describes the behavior of these materials until the moment when their load-carrying capacity vanishes completely.
