This paper presents two optimisation-based methodologies to calibrate material parameters for such simulations. The processes combine computations with a set of optimisation 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.
