Based upon shear strain gradient plastic theory of rock deformation localization, it is assumed that the failure pattern of rock in the shear band is shear failure.
假设剪切带内部的岩体为剪切破坏 ,利用剪切应变梯度塑性理论 ,解析得出了考虑围压和孔隙压力的岩石试件应力与应变的关系 ,解析解与众多的实验研究结果比较一致 ,围压效应和孔隙压力效应是局部化所致 ,这一研究结果对于自然灾害的防治有一定的理论和实际意
The fragment ratio of tension and shear fracture of 50SiMnVB cylinder shell under explosive load is investigated.
试验中还观察到在拉伸断口应力方向的断面上出现了熔化现象,这说明在拉伸断裂区局部存在着剪切现象,同时证明采用高能束改性后圆筒在爆炸载荷作用下可产生全壁厚剪切断裂。
A macro and micro and chemical element analysis was made on fracture of ruptured coupling bolts,torsion test was performed and stress analysis and calculation were made,the results show that when the steam turbine had failure,MP-LP rotor coupling bolts and generator-exciter rotor coupling bolts failure were classified as overload shear fracture with partial deformation .
对215MW汽轮机断裂的对轮螺栓做断口宏观、微观分析,化学元素分析,扭转试验及受力分析计算,结果表明汽轮机组在事故中,中压-低压转子对轮螺栓和发电机-励磁机转子对轮螺柱的失效类型为:过载剪切断裂,同时局部挤压变形,这是由于事故过程中轴系受到冲击扭矩作用而引起的。
