Recently, many researchers have investigated helmet design with respect to helmet performance in shock absorption tests. The finite element method contributes greatly to helmet test modeling. Finite element simulations are also indispensable to evaluate head injury criteria. This study performs finite element analyses of helmet impact tests using LS-DYNA software.
