| Abstract: | 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. |
