摘要
本文讨论非金属材料在外力作用下产生的断裂类型,断裂机理和三种开裂类型的判别式,结合具体实例进行了计算,并与其它强度理论进行了对比,认为Griffith 强度理论对于非金属材料的断裂问题判据是适用的.
In this article, fracture of non-metal materials under external force is dis cussed,i.e. fracture type,fracture mechanism and three formulas for judging fracture types. Practical calculation was made Griffith's strength theory has proved more applicable for judgement of fracture as compared to other theory.
