Application of AM60B Magnesium Alloy Material Model to Structural Component Crush Analysis

Simulations of energy absorbing structural components made of die cast magnesium alloy AM60B under axial crush and bending conditions require determination of accurate material parameters when using finite element (FE) analysis. This paper presents two optimization-based methodologies to calibrate material parameters for such simulations. The processes combine computations with a set of optimization procedures to systematically adjust the material input parameters until the calculated mechanical responses optimally matched those measured experimentally. Results indicate that material input generated from these procedures replicates both experimentally obtained force-deflection curves and material fracture pattern well, thus enhancing model predictability in crashworthiness using AM60B.
