Abstract
The paper describes a ductile damage model for
orthotropic metals. The ductile failure of metals is an important phenomena
in crashworthiness, impact and shock problems, and therefore must be
considered in structural simulations. The model is based on an orthotropic
damage matrix which is incorporated in the constitutive equations for stress
update and provides degradation of material properties. The evolution of the
damage matrix assumes the growth and coalescence of voids. The
implementation of the model for both continuum and shell elements is
discussed. Finally the model is demonstrated on test problems.
