In order to study the residual stress profile of 7050-T7451 aluminum sheet with groove after laser shock peening (LSP). the residual stress distribution was measured. It is shown that the residual stress decreases gradually from the center to the edge of groove; and then there is the minimum value at the edge of the groove bottom surface. By using ABAQUS software to establish three-di... https://www.socialstudiesscholar.com/
