This document summarizes an engineering optimization project that aimed to minimize the displacement of a rectangular plate impacted by a rigid ball. Finite element analysis was performed using LS-Dyna before and after topological and sizing optimization using Genesis. The optimization increased the plate thickness up to 10 units and reduced the central displacement by 59.6%, achieving the objective of increasing plate stiffness to impact loads. Design visualization and evaluation was done using LS-Dyna, Genesis, and the Design Studio interface.
