Abstract:

A practical three-dimensional viscoelastoplastic constitutive law is developed. It is applicable to interior points as well as to boundary points where certain of the stress components may be prescribed by boundary conditions. The calculational procedure is suitable for direct inclusion into finite difference codes and has been incorporated into the GENERAL code. Numerical results are presented. For missile structural lethality and vulnerability problems, material damping tends to result in three-dimensional response decaying to two dimensional shell-like response after only a few skin thickness transits.
