摘要

摘要: 从完全的虚功和虚功率原理以及广义Piola定理出发一并推导出非局部非对称弹性理论的运动方程、所有边界条件和全能量方程.把这里给出的边界条件和高键,戴天民的相应结果加在一起即可表述非局部非对称线性弹性理论的混合边值问题.

Abstract: In this paper,the equations of motion and all boundary conditions as well as the energy equation for non-local asymmetric elasticity are derived together from the complete principles of virtual work and virtual power as well as the generalized Piola theorem.Adding the boundary conditions presented here to the results by Gao Jian and Dai Tianmin,the mixed boundary-value problem of the non-local asymmetric linear elasticity are formulated.
