通过CAERSARⅡ计算一段简单的L型自然补偿管道,为什么结果里面的许用应力Allowable老是为0?求高手解决! 且在前面的错误检查里有这样一条warning: BEND ISSUE at: 30 the fitting has a D/t ratio greater than 100. SIF computations for this fitting may be invalid.

warning: bend issue at: 30 the fitting has a d/t ratio greater than 100. sif computations for this fitting may be invalid. 指的是你的管道是大直径薄壁管道,因为存在管道椭圆化的问题,所以sif系数caesarii 算出来可能不准确
