A Simple Crack Extension Criterion for Time Dependent Spallation.

Abstract

A simple mechanistic model for time dependent spallation is developed and correlated with experimental data. Included in the model are effects of plastic flow and strain rate sensitivity. Experimental data for two aluminum alloys are consistent to within about 30 percent of the critical stress predictions for this model. (Author)
