- •
The residual contact pressure due to hydraulic expansion is estimated analytically taking into account reverse yielding.
- •
Bauschinger effect is found to have a significant effect on the reduction of residual contact pressure.
- •
Comparison of the analytical model and FEM are in good agreement.
- •
Isotropic hardening and Tresca yield criteria overestimate the contact pressure.
