Abstract

Strain-hardening behavior for plane stress problems is modeled by a panel with n layers, the first (n - 1) layers are elastic-perfectly-plastic under Mises-Hencky condition, each with different yield stress, and the n-th layer is elastic. Equivalent incremental stress-strain relations for the panel can be obtained. The resulting uniaxial stress-strain curve contains n segments. Those segments in the plastic range are not straight lines.
