摘要
给出了一种无须计算主方向角数值即可直观定性确定平面应力状态下主方向大致方位的简单规则,并从主点法角度出发对此规则作了证明,最后还对此规则的应用作了详细阐述。
The paper presents a simple rule of visual determining main direction's general position without calculating the value of main direction's angle. Starting from the Main-point Method,the explanation of the rule is given and the application of the rule is expounded.
