Experimental studies and simulation were carried out on laser shock marking.

Simulation and Analysis of laser shock forming process of sheet metal;

Study of the effect of laser shock processing on titanium alloy;

The basic principle of laser shock forming was described and the influences of some factors on the deformation results of TA2 sheet were simulated by ABAQUS.

Experiment with QT700 crankshaft by laser shock processing;

Effect of coating on titanium alloy during laser shock processing;

Fracture characteristic of Al_2O_3 ceramics by strong laser shock processing;

When power density was 5 ×1012W/m2, the peak stress of the shock wave induced by laser shocking exceeded the dynamic yield strength of the aluminum alloy 2024T62,which caused high density dislocations and stable residual compressive surface stresses in the laser-shock-processed are.

This paper describes the experimental apParatus of laser shocking,the chemical compositions and mechanical properties of aviation aluminium alloys 7475T761 and 2024T62 and the shapes of laser shocked test pieces.
