Ductile damage plays a significant role in many forming processes which induce
large strains. Coupled damage-plasticity models have become quite successful at
predicting the underlying porosity initiation, porosity growth/coalescence and localized
deformation. In the present paper we adopt a scalar damage variable which
isotropically affects the elastic and plastic response of the material. The model is
fully nonlocal to avoid pathological localisation effect. Here we focus on its implementation
in a three-dimensional tetrahedral element.
