plastic strain. The kinematic hardening modulus is linear, and for temperature independent anal-yses it requi res only two stress -strain pairs for its definition: the yield stress at zero plastic strain and a yield stress at a finite plastic strain value.

Hyperelastic materials in ABAQUS
The initial shear modulus and bulk modulus are given by: In contrast to materials that exhibit linear elasticity, the stress-strain relationship of a neo-Hookean material is not linear. Instead, the material initially follows a linear relationship between applied stress and strain, but eventually reaches a plateau.
