... results, and the role of dislocation obstacles is interpreted in terms of their spatial density. Simulations provide insight into yielding and plastic deformation of indented single-crystal materials, and establish a basis for developing coarse-grained plasticity models of localized contact deformation...

... is elastically confined, being on the order of the elastic yield strain. The residual plastic zone is hypothesized to have a penny-shaped configuration (of radius a and height h ). The effects of the impinging balls are considered as non-interactive. Multiple impacts of the balls...
