Finite Element Analysis of Residual Stress in Ti-6Al-4V Alloy Plate Induced by Deep Rolling Process under Complex Roller Path

Figure 9

Mises stress distributions on the plate upper surface (top-view in the left-hand column) and in the plate (cut-view in the right-hand column) when the roller spins (a) 0.5-revolution, (b) 1.5-revolution, (c) 2.5-revolution, and (d) the roller is at the end of recovery step. Note that the roller is removed from the figure in order to see the stress distribution completely and all units are in Pa.
