Notes:
Laser shock peening (LSP) is an innovative surface treatment technique for metal alloys,with the great improvement of their fatigue, corrosion and wear resistance performance. Finiteelement method has been widely applied to simulate the LSP to provide the theoretically predictiveassessment and optimally parametric design. In the current work, 3-D numerical modellingapproaches, combining the explicit dynamic analysis, static equilibrium analysis algorithms anddifferent plasticity models for the high strain rate exceeding 106s-1, are further developed. To verifythe proposed methods, 3-D static and dynamic FEA of AA7075-T7351 rods subject to two-sidedlaser shock peening are performed using the FEA package–ABAQUS. The dynamic and residualstress fields, shock wave propagation and surface deformation of the treated metal from differentmaterial modelling approaches have a good agreement
