Abstract This is the second in a two-paper series examining the elastic-plastic deformation of a metallic target material under repeated impact. This paper examines the effect of statically cyclic loading on copper and numerical calculations have been performed up to ten cycles. The extent of the loading phase in each cycle is specified by a constant external work done by the indenter. The deformed configuration of the target material, the locus of material flow, and elastic-plastic boundaries due to cyclic loading are presented. There is a saturation of the stress field near the bottom of the indented crater after the first few cycles of loading. A residual tensile stress field in the direction normal to the target surface exists underneath the indenter in every cycle, which is responsible for the formation of subsurface layer cracks. Results of the coefficient of restitution obtained from the analysis and experiments are also presented.
