LARGE DEFORMATION SYMMETRICAL ELASTICITY PROBLEMS SOLVED BY THE VARIATIONAL METHOD

In this paper, based on the mathematical theory of classical mechanics and Chen's theorem, the variational method was used in the study of large deformation symmetrical elasticity problems. The generalized variational principles of potential energy and complementary energy based on the instantaneous configuration were obtained, and the equivalence between the two principles was proved. Besides, the generalized variational principles of dynamical problems based on the instantaneous configuration were also given.
