摘　　要：基于连续介质力学随体导数的概念,以随体微分代之以随体导数,应用于弹性体应变分析中,得出了弹性体任意两斜方向间角应变的一个公式,并对该公式的正确性进行了验证.Based on the concept of material derivative for continuum mechanics, using material differen tial in place of material derivative and applying it to strain analysis of the elasticity solid, a formula of shear strain between two arbitrary oblique directions in the elastic body was obtained, the accuracy of the formula was also verified.

关 键 词：弹性体 随体导数 随体微分 斜方向 角应变
