Redistribution of residual welding stresses under the effect of normal incident shock wave

V.G. Petushkov

E.O. Paton Electric Welding Institute of the NASU 11 Kazymyr Malevych Str., 03150, Kyiv, Ukraine.

Abstract
Interaction of normal incident shock wave with the field of internal stresses in metal is considered. It is shown that under rational conditions of loading of structural steels this correction is about 5 % of the wave amplitude. Therefore, it can be ignored in practical calculations.
Keywords: residual stress, explosion treatment, stress relief, shock wave, dynamic yield stress, elasto-plastic strain
