Behavior and Sustainability of Laser Shock Peening Induced Residual Stresses in Complex Fatigue Loading

Abstract

The mechanical soundness with which an engineering structure performs under applied loads defines its structural integrity. In an engineering structure, mechanical fatigue is the temporal response of structural integrity under varying applied loads. Under loading conditions leading to mechanical fatigue, such a temporal response may be characterized by a gradual deterioration in structural integrity. Under those conditions which lead to continued deterioration, a catastrophic failure may manifest even when the applied loads are well within safe limits. Consequently, structural integrity and the various environmental, loading and material factors affecting it have gained great significance in the aerospace industry.
