What is it about?
In the paper the modified Gurson model is developed for the simulation of damage growth and ductile fracture under low, medium and high stress triaxiality loadings. A new coalescence criterion is introduced based on a simple assumption that singular value of the effective stress triggers the coalescence of microvoids in ductile materials.

Why is it important?
The area of the application of the modified Gurson model is specified in the article. The modified Gurson model is the most versatile tool for predicting the growth of ductile damage.
Perspectives
The modified Gurson model is a good addendum to other models of damage development, which are formulated by means of phenomenological research methods.
