The contribution aims at assessing different computational models for their
capabilities in describing the initiation and growth of ductile cracks at
the constituent level in inhomogeneous materials.
The main emphasis is put on the ductile damage models of Gurson and Rousselier
and on a fully coupled ductile damage indicator model.
The models were implemented via user subroutines into the Finite Element code
ABAQUS/Standard, a nonlocal approach being used to overcome their well-known
