A constitutive model is developed for strain rate dependent foam and implemented in an explicit dynamic finite element code. The constitutive model is developed in conjunction with a Lagrangian hexahedral solid element with twenty four degrees of freedom. A number of dynamic impact problems involving strain rate dependent foam are analyzed and results are compared with experimental data. In all cases, numerical predictions show excellent agreement with the experiments.
