摘要
本文基于非局部连续统场论的公理系统,建立了具有非局部体力矩作用的非局部弹性理论,我们证明了,在非局部弹性固体中存在着非局部体力矩,非局部体力矩引起了应力的非对称和非局部体力矩是由材料中的共价键产生的。
In this article, a theory of nonlocal elasticity with body moments is developed on the basis of axiom system of nonlocal continuum field theory. It is shown that there is the nonlocal body moment in the nonlocal elastic solid and the stress asymmetry is the result of the body moment, which is caused by the covalent bonds in material.
