The paper presents the features of applying the methods of dimension analysis and finite element simulation in relation to the processes occurring during laser shock processing (LSP) of titanium alloys with the shape memory effect (SME). It is found out that the main dimensionless parameters that control the depth of the plastic zone that occurs during LSP are the dimensionless duration of the laser pulse and the peak pressure in the shock wave. A comparative assessment is made between the simulated dependence of the dimensionless depth of the plastic zone on the dimensionless peak pressure in the shock wave and the corresponding experimental studies from the existing publications.
