ABSTRACT
A new arbitrary reference configuration (ARC) elasticity theory is proposed in the paper for finite strain dynamic applications with both the attempt to circumvent the deficiencies associated with the hyperelasticity and hypoelasticity theories. The corresponding stress update formulation and the ARC Lagrangian formulation is also developed. Some numerical examples are shown to demonstrate the effectiveness of the proposed theory.
