Simulation of Ductile Failure in Metals Under Dynamic Loading Conditions Using Advanced Material Damage Modeling

Abstract

This report results from a contract tasking University of Cassino as follows: The contractor shall investigate the issue of advanced failure prediction and design by means of innovative material failure modeling and computational techniques. The specific tasks include: - the use and implementation of advanced material modeling incorporating damage. strain rate and temperature effects. in an extensive number of numerical simulations; - verification of the model effective predictive capabilities in a number of applications; - extension of the material model in order to incorporate advanced features needed in penetration mechanics simulations: - development of analytical tools to measure material response to high strain rates loadings using a simple instrumented Charpy pendulum.
