Notes:
3A21 metal sheet was shocked by Nd-glass laser in oblique angle under the function ofpulse energy 42 J, pulse width 23 ns, pulse power 1.2×109 W, the angle between input beam andnormal of sample is 30°. The center of the deformation of the sheet is 3 mm away from thegeometric center. Residual stresses of crossing center side in length direction and the distribution ofspace in the positive and negative sides are measured by XRD, which are compressive stress 100MPa. The diagonal length of the sheet is longer than the one of the crossing center side in lengthdirection, the force that needs to form in the diagonal direction is bigger, so compressive stress ismuch bigger. The capstone of the square sheet is squeezed, the procession seriously increase, socompressive stress is the biggest one
