Abstract Effects of Laser Shock Processing (LSP) on mechanical properties of TC4 titanium alloy blades were numerically evaluated. Finite element models were developed to simulate the residual stress distributions and energy profiles on the TC4 titanium alloy blades under different power density inputs during LSP. The models were validated by comparing the simulation results with the experimental results. Simulations show that the kinetic energy of the blade reaches the maximum value within 0–70 ns. The residual stress distribution results exhibit the decreasing compressive residual stress along the radial direction as well as along with the increased depth. The microstructure of the TC4 titanium alloy blades after LSP from transmission electron microscope (TEM) indicates that simulation results were reasonable.
