The ExpJ2 class.
The ExpJ2 class defines a 3D material model using the J2 yield criterion. There is no kinematic hardening defined so parameter \(beta\) only controls the amount of isotropic hardening, which is defined using the following expression
\begin{align} \sigma=\sigma_y\left(\left(1+a\right)\exp\left(-b\varepsilon_p\right)-a\exp\left(-2b\varepsilon_p\right)\right) \end{align}
where \(a\) and \(b\) are two parameters.
If \(a>1\), hardening are defined, the ratio \(\sigma_m/\sigma_y=\dfrac{(1+a)^2}{4a}\).
