# Application of Chien’s Theorem to the Establishing of General Variational Principle in Polar Elasticity of Finite Deformation

• Publish Date: 1981-04-15
• Variational principles of minimum potential energy and complementary energy of linear polar elasticity has been formulated by No,packi[3].As it has been proved by Chien Wei-zang, that the tveo generalized variational principles are equivalent in functionals; we now apply this important statement Chien's theorem, and Lagrange's method of multiphers to the establishing of generalized variational principle in polar elasticity for finite deformation. The fundamental equations of mechanics of finite deformation used are of which has been established in the author's paper[7],[4].
