摘要
本文证明了在任意方向的应变计算中不能简单地应用平面上的应力公式进行对应变换.推出了在以使直角减小的剪应变为正和以使直角增大的剪应变为正时相应的剪应变新公式.
The paper has proved that in the strain calcalation of random directions, the plane stress formula cannot be used so simply to carry out the corresponding shift, and it is deduced that the corresponding new formula of shearing strain. When the shearing strain decreases, the right angle is positive and when the shearing strain increases the right angle is positive.
