作者：
Highlights：
• The differential type elasto-plastic model with mixed hardening describing the in-plane stress state.
• The update algorithm to solve the model, based on the radial return algorithm adapted to the in-plane stress.
• The discretized weak formulation of the non-linear elastic-type problem; finite element implementation.
• The algorithmic elasto-plastic tangent moduli rebuilt to solve the non-linear system for displacements.
• Comparison of the Simo solution and the in-plane stress solution applied to a trapezoidal plate.
