Web12 mai 2024 · I made some tests: ls-dyna + bilinear kinematic hardening st structural + multilinear kinematic hardening with the same mesh and loads. ls-dyna showed a margin of safety of 1.01 st structural showed a margin of safety of 0.7 Now I want to figure out which is more accurate. 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.
