摘要 针对常见的化工设备及化工管道焊接结构,利用ABAQUS软件对典型的双材料焊缝中心裂纹紧凑拉伸(CT)试样的蠕变断裂,进行了大量有限元分析计算,并通过工程实例进一步验证了胡兆吉提出的蠕变断裂参量C*工程估算方法的适用性。 As for familiar weldment structure of chemical equipments and pipes,plenty of finite element analytical calculations were carried out for creep crack of typical bi-material CT specimen with crack in the weldment center using ABAQUS software,and the applicability of the technical estimation method for creep crack parameter C＊ put forward by HU zhao-ji was validated furtherly through technical example.
