本文用应力圆证明了平面应力状态下的应力互换定律,并根据应力互换定律和应力圆导出已知任意两个斜面上的应力求解主平面和主应力的解析公式,即给出计算主平面和主应力公式的普遍形式。
In this paper, the law of stress exchange under plane stress is proved by the stress circle. According to the law of stress exchange and the stress circle, the analytical formulas for solving the principal plane and principal stress of any two known slopes are derived. The general form of plane and principal stress formulas.
