Introduction

An industrial application of the cradle to grave modeling effort pursued at CAVS is presented in this chapter. The experimental and numerical analysis of a Magnesium component provided by General Motors shows the robust methodology developed by our researchers to predict the behavior of a structure under precisely defined boundary conditions. More specifically, the study is about an AZ91 magnesium alloy, die cast, shock tower under monotonic load-to-failure conditions. The goal is to numerically determine the failure location using a validated microstructure-property based material model.
