平面应力状态中任意方向面角度取值范围的分析

摘要

The range regulation of arbitrary direction in plane state of stress is beneficial to the calculation of normal stress or shear stress and is benefit to specify the angle selection of principal plane and extreme value direction plane of shear stress.%规定平面应力状态中任意方向面角度取值范围,有利于计算平面应力状态中任意方向面上的正应力与切应力,有利于规范主平面和平面内切应力取得极值方向面角度的取值。
