The numerical representation of structural material response which includes damage for computational applications is an evolving length scale problem. Present approaches rely heavily upon proper physical basis for the equations employed and consideration of the limitations of the numerical framework. Material damage is also much less homogeneous than the elastic-plastic response of materials mechanical loading. This talk will discuss some of the important aspects of modeling the ductile damage response of metallic materials – for both pore and shear band based behaviors. The formation of adiabatic shear bands involves specific aspects of a material response which require material softening mechanisms which are not yet fully understood for the conditions of rapid loading. The formation and growth of pores is influenced by local material structural factors which we are just now beginning to probe quantitatively. Recent work in these areas will be discussed as well as envisioned future needs.
