摘要
本文首先引进了在微小变形情况下弹性体中应变向量的概念,并指出一点处的应变状态可用该点处应变向量的投影形式来描述,然后对各向同性弹性体给出了应变向量和应力向量间的关系,进而推出了应变向量和应力向量重合及材料是不可压缩和条件。
This paper first gives the definition of strain vector in elasticity body which is in small deformation, and points out that the strain state of point in the body is described by-projection forms of the strain vector at this point, and then gives relation between strain vector-stress vector for isotropic elasticity body, moreover derives conditions that strain vector coincides with stress rector and the material is incompressible.
