| Abstract: | In this paper, a new proposition of principle of minimum potential/stationary complementary energy for nonlinear elasticity is given. And based on this new proposition, a new three field generalized potenital/complementary principle for nonlinear elasticity is established by applying linear Lagrange multiplier method to relax all variational constraint conditions including nonlinear stressstrain relation. |
