Abstract

A brief review of the methods for the study of residual process stresses (RSs) in the elements of structures and specimens is given. The possibilities and the fields of the application of nondestructive testing of RSs are indicated. Destructive experimental and calculation methods for the study of two-dimensional and three-dimensional nonuniform fields of RSs in spatial structures, which are based on the interpretation of experimental data as an inverse problem of elasticity theory, are particularly noted. It is recommended to use optical-digital methods for the recording of displacement fields in order to obtain significant collections of experimental information necessary in this case, which are caused by the formation of the cuts of various configurations in the object under study.
