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. Web1 sept. 2024 · Another characteristic feature of the cyclic behavior of IN718 is the mean stress relaxation, σ m = (σ m a x + σ m i n) / 2, that appears during non-symmetric cyclic deformation under strain control (e.g. R ϵ = ϵ m i n / ϵ m a x = 0), Fig. 1 (b). This response is a consequence of the kinematic hardening and implies a reduction of the mean stress …
