WebThe multilinear kinematic model, available only in Abaqus/Standard, combines several piecewise linear hardening curves to predict the complex behavior of materials. This model is very easy to calibrate and is defined by giving the value of the uniaxial yield stress as a function of uniaxial plastic strain, temperature, or field variables. Web31 iul. 2024 · Hi @skadam- Kinematic hardening is one of the hardening rules that describe the behavior of material after reaching yield surface. In the principal coordinate system, for kinematic hardening, the yield surface remains the same shape and size but merely translates in stress space. July 31, 2024 at 3:35 pm Ashish Khemka Ansys …
