Abstract

The mechanical fatigue behavior of (PMMA) poly(methacrylate) under shoot peening was investigated under room temperature and stress ratio R =−1 using rotating bending tests. The fatigue life of specimens was increased up to 5 min. Shot peening test (SPT) and then it reduced. Also at the same SPT (5 min) the endurance fatigue limit was raised by 300% compared to the dry fatigue. The hardness and roughness were increased when the SPT increased. The control factor which affects the fatigue life was the roughness after 5 min, shot peening.
