Whereas in part I of the paper , we laid down the foundations towards a new arbitrary reference configuration (ARC) framework for computational elasticity finite deformation applications, here in part II of the paper we extend the developments to computational elasto-plasticity. Within the context of the ARC framework, the mid-point rule and the trapezoidal rule for computational plasticity are further investigated. The conclusions that the trapezoidal rule is indeed more suitable for computational plasticity in comparison to the mid-point rule, and the fact that the present ARC framework is more suitable for finite deformation problems in comparison with the widely adopted total Lagrangian formulation and the updated Lagrangian formulation, are finally drawn and established.
