RATED GENERALIZED SUB-REGION VARIATIONAL PRINCIPLES IN NONLINEAR ELAS TODYNAMICS

Abstract

Abstract: In this paper, the rated generalized sub-region mixed and hybrid variational principles in nonlinear elastodynamics are constructed on the basis of Co-Moving coordinate description and S-R decomposition theorem, which contain five independent arguments, or velocity gradient, momentum, velocity, stress and strain rate.

Key words: rated generalized sub-region, mixed and hybrid variational principle, Co-Moving coordinate description, S-R decomposition theorem
