First of all, this paper gives Legendre transformation for the so-called partial corresponding variables of strain energy function Σ(Eij) and complementary strain energy function Σc(Sij) of the elastic materiel, and introduces the corresponding blending complementary strain energy function Σchk! and blending strain energy function Σhk!. Moreover, a series of generalized variational principles of the corresponding blending energy form of non-linear elasticity is given. As a special case, there exist corresponding results[1] in linear elasticity. 相似文献

非线性弹性理论的混合能量形式广义变分原理 总被引:1,自引:0,他引:1
本文首先对弹性材料的应变能函数∑(Eij)和余应能函数∑C(Sij)的部分“对应”变量作Legendre变换,引进“对应”的混合余应变能函数∑klC和混合应变能函数∑kl。进而,给出非线性弹性理论的各种“对应”的混合能量形式广义变分原理。线性弹性理论也有相应结果,它是本文结果的特殊情况。 相似文献
