Zusammenfassung:	The technology of laser shock processing of titanium alloys with the shape memory effect is simulated using the finite element method and dimensional analysis. In total, 16 independent dimensionless parameters characterizing the mechanical behavior of shape-memory NiTi alloys are analyzed. The dependences of the influence of the dimensionless duration of the laser pulse and the dimensionless peak pressure in the shock wave on the dimensionless depth of the plastic zone are obtained.
