摘　　要：首先介绍了压力容器及管道缺陷评定的常用方法,即应力强度因子法和J积分法;然后阐述了ANSYS在压力容器及管道缺陷评定时的一般步骤;最后针对二维裂纹和三维裂纹进行了应力强度因子和J积分计算,并与手工计算值进行了对比。结果表明,应用ANSYS对压力容器及管道进行缺陷评定是安全可靠的。Firstly, introduced the common methods for defect assessment of pressure vessels and pipelines,including stress intensity factor method and J-integral method. Secondly, illustrated the general steps of defect assessment for pressure vessels and pipelines by using ANSYS software. Finally, calculated the stress intensity factor and J-integral of two-dimensional and three-dimensional cracks, and compared the values with that from manual calculation. The results showed that the defect assessment of pressure vessels and pipelines with ANSYS software was safe and reliable.
