Simulation and modeling of the penetration of brittle-ductile assemblies under large deformation

Abstract

This paper is written as an educational note for material scientists and engineers interested in predictive modelling of large strain deformation of brittle-ductile assemblies. Such assemblies often include residual stresses from manufacture. Computational procedures are discussed for modelling residual stresses prior to dealing with the more complex problem surrounding penetration mechanics. The inclusion of quasi-brittle fracture is considered. The presented techniques are considered relevant to micro-indentation of brittle ductile assemblies.
