This report describes the implementation of the Chaboche type Nonlinear Kinematic Hardening Model developed for the PNGV SPP (Partnership for the Next Generation Vehicle, Spring-back Predictability Project). The material model includes a nonlinear kinematic and isotropic hardening law, transverse anisotropy, strain range memorization for cyclic hardening/softening and viscoplasticity. This report is a companion to the report: ''A Return Mapping Algorithm for Cyclic Viscoplastic Constitutive Models'' which concentrates on the theoretical aspects of the model. This report summarizes the necessary parameters for the model, briefly discusses their interpretation and shows some numerical simulations. The report also specifies the data structure requirements for linking the material model software by explicitly referencing the source code delivered to the SPP collaborators.
