Detailed Description

The ArmstrongFrederick1D class defines a nonlinear hardening material with mixed hardening (isotropic and kinematic) based on J2 plasticity rule.

The isotropic hardening is defined as an exponential function.

The kinematic hardening consists of multiple Armstrong–Frederick type back stresses.
