本文简述了带裂纹容器和管道的失效分析方法。简介了一些从不同失效理论出发而得到的失效压力计算方法,并与部分实验结果进行了比较。结果表明,这些方法对由韧性好的材料制造的具有纵向裂纹(l>2di)的容器,计算结果与实验值较为吻合。
This article briefly describes the failure analysis methods for cracked containers and pipes. Some methods for calculating the failure pressure obtained from different failure theories are introduced and compared with some experimental results. The results show that these methods are in good agreement with the experimental results for containers with longitudinal cracks (> 2di) made of a tough material.
