摘要
文章在有限变形分析基础上建立了对复杂结构进行弹塑性断裂评定的工程方法,用以修正COD设计曲线。提出了压力容器安全评定的三判据法,并通过实物容器试验进行了验证。同时对新的弹塑性参量T积分开展了探索性研究。
In this paper, an engineering assessment method of elastic-plastic fracture based on finite deformation analysis of complex structures. or a modified COD -design equation, presented forward is put. A put forward three-criteria safety assessment method for pressure vessels. Full-scale pressure vessels were used in order to verify the method proposed. The new elastic-plastic fracture parameter T-integral is used in experimental exploration studus.
