Abstract: Recent advances in experimental techniques have enabled impact tests of ultrathin films. For example, microprojectile impact tests of ultrathin polymer films have revealed that their specific penetration energy is about ...

Abstract: We conducted large-scale molecular dynamics (MD) simulations of shock wave propagation and spallation in amorphous polyurethane and polyurea. First, we computed the shock Hugoniot of the polymers using the multiscale shock ...

Abstract: We investigated the temperature and strain rate dependent fracture strength of defective graphene using molecular dynamics and an atomistic model. This atomistic model was developed by introducing the influence of strain ...
