Abstract
In two previous papers, the authors presented results of a new process of introducing beneficial residual stresses in a sheet metal strip containing a small circular hole by a single thermal shock applied over an annular region concentric with the hole. In this paper, it is shown that multiple thermal shocks over separate annular regions are considerably more advantageous in introducing such beneficial residual stresses in the same sheet metal and in permitting wider tolerances for such variables as locations, sizes of shock zones, and strengths of the shocks for desired degree of benefit.Keywords
