断裂力学对压力容器标准的影响,主要是讨论它的应用、局限性及有关的科研内容。现行的压力容器规范中,多数都将设计和检验要求分开考虑。但由于所有构件都不可避免地会有缺陷,因此在设计时就应考虑到有限度的缺陷尺寸的存在。断裂力学的技术正好为 The influence of fracture mechanics on the standard of pressure vessels mainly discusses its application, limitations and relevant scientific research content. The current pressure vessel code, most of the design and inspection requirements will be considered separately. However, due to the inevitable imperfections of all the components, a limited amount of defect size should be considered in the design. Fracture mechanics just right
