本文利用广义裂纹尖端位移理论,并考虑到裂纹尖端拉应力场与剪应力场及其膨胀效应的影响,从而对有斜裂纹压力容器的断裂问题进行了探讨,给出了高强钢和中低强钢材质压力容器的断裂压力计算式及短裂纹流变断裂压力的判据。
Based on the generalized crack tip displacement theory and considering the effect of the tensile stress field, the shear stress field and its expansion effect at the crack tip, the fracture of the pressure vessel with oblique cracks is discussed. Fracture Pressure Calculation Criterion of Steel Pressure Vessel and Rheological Fracture Pressure Criterion of Short.
