Abstract
Procedure of approximate calculation of stresses and strains in the trace formed in a relaxing material by a single shock-wave compression is described. The results obtained can be used in determination of parameters of explosion loading to relieve the residual stresses in welded joints of metal structures
Keywords: residual stresses, explosion treatment, relaxation of stresses, stress-strain trace, shock wave
