2. Effect on mechanical properties
2.1 General
When a part is subjected to an elastic residual stress field characterized by a tensor on which is superimposed a service stress field defined by the tensor σ S , the actual stress to which the part will be subjected will be characterized by the tensor σ R + σ S (figure ). If residual stresses are added to service stresses (tensile residual stresses, for example), the part is locally overloaded due to residual stresses. If, on the other hand, residual compressive stresses are introduced by a mechanical surface treatment operation...
