Elastoplastic indentation of a half-space by an infinitely long rigid circular cylinder

Abstract Using the finite element method the authors performed a detailed study of the elastoplastic indentation of a half-space by an infinitely long rigid circular cylinder having its axis parallel to the half-space surface. An elastic-constant strain-hardening law was assumed for the constitutive equation of the half-space material. The analysis covers the region from the maximum elastic contact load to a state where this load has been increased eightfold in some cases. The results are given for different strain-hardening slopes and the analysis is limited to plane strain deformations. The residual depths of indentation obtained in this analysis agree reasonably well with published experimental data.
