14.1. Characteristics of modeling

The law of behavior tested is” VISC_CIN2_MEMO “[R5.03.04]. It is a Chaboche law comprising two variables for non-linear kinematic work hardening and modeling the memory effect. (see modeling \(I\), with the addition of viscosity parameters: \(N\), \(1/K(T)\) and \(1/M(T)\).
