用破坏面的方法对材料的诸强度理论进行研究。不同的强度理论在偏平面内有不同形状的破坏面,结合文献[3]提出的材料极限强度计算公式,对三轴抗拉强度不能控制等问题作了分析探讨。
The method of destroying the surface was used to study the strength theories of the material. Different strength theories have different shapes of failure surfaces in the plane of deflection. Combined with the formula for the ultimate strength of materials proposed in [3], problems such as the failure to control the triaxial tensile strength are discussed.
