Abstract
This article study the dynamic fracture behavior of compact tension specimens under tensile wave loading[1-3]. And the test - numerical hybrid method is used to satisfy the condition of dynamic stress equilibrium. The initial load for numerical simulation is based on the experimental data. In that case, the numerical simulation results can be used to analysis the dynamic stress equilibrium.
