- Abstract:
-
The effect of surface damage, such as dents caused due to the low velocity impact of hard blunt objects, on the fatigue life of mechanical components are investigated in this paper. A twodimensional dislocation density approach is used to obtain the stress intensity factors of a crack propagating under dents. Both the contributions of the geometrical stress concentrator (notch), due to the presence of the dent, and the residual stress field, generated during the impact, on the stress intensit...
