Abstract

The stresses existing in an elastic body in the absence of external forces or loads (thermal or mechanical) are termed as residual stresses. This can be appreciated further from the schematic illustrated in Fig. 10.1 which shows an irregular externally loaded two dimensional body. The external forces or loads are denoted by symbol F_i, where i = 1–5 and acts on a small region indicated by A. After removal of external forces or loads, two possible scenarios for the region denoted by letter A are: (a) there are no internal stresses, and (b) there are internal stresses present in the absence of external loads F_i. The stresses within the body in state (b) are termed as residual stresses.
