摘要：

The finite element ANSYS/LS-DYNA was applied to simulate the propagation characteristics of stress waves in laser shock processing (LSP) for DD6 single crystal alloy materials. The constitutive model of dynamic response and computational modeling of LSP was built in this paper. Results of numerical simulation indicates that the change of stress waves was mainly appeared to the first wave, and the time with fluctuation was expanded slowly with the spread depth of stress wave was increased. The results can be used as theoretical basis for optimizing the process parameters in laser shock processing.
