Residual Displacement and Strain Profiles in 3D Rolling Contact on an Elasto- Plastic Body with Isotropic or Kinematic Hardening

摘要

For a circular point contact (k = 1) the residual imprint is significantly higher for kinematic hardening than for isotropic hardening. It stabilizes after a few cycles for isotropic hardening while it keeps on increasing for kinematic hardening. A change of the residual imprint geometry is also observed at the unloading point after rolling.
