  Lemaitre's ductile damage model and a simplified variant excluding kinematic
hardening were studied and implemented into computer code. For purposes of
verifying the model, results from computations with the finite element method
are compared to literature. It is found that the behavior expected from theory
is modeled by both implementations. Quadratic levels of convergence were
observed for the simplified model, while results show that convergence of the
kinematic hardening implementation deteriorates with damage. It is concluded
that further examination is needed to verify the correct implementation of the
kinematic hardening model.
