Hi All,
While doing stress analysis for a padeye hole or lifting lug, there are huge stresses on the padeye holes itself. But when we do hand/manual calculations, the stresses are far more less and easily passes. Can someone please advise the reason/logic behind this please?

JM,
I am not being able to attach anything. There is no attach icon here.

When replying to a thread - click on the Advanced Editor upper right corner of the dialog box.
As I type this - I don't see it using IE, so try Chrome instead.
Then you can attach files.
sounds like a stress concentration or singularity. lots of good discussions about them here in the forum but basically you will want to improve the mesh , add a filet or if necessary add the next component
这是一个应力奇异点的问题，我在工作时也遇到了这个问题，我想，可以从两个方面解释一下，首先，在应力最大处模型有明显的转折，会出现奇异点，可能是有限元分析原理造成的，具体我就不解释了。其次，还要考虑拉应力与压应力的问题，我们知道，材料收到的压应力的数值会非常高，是材料屈服的数倍。

This is a stress singularity problem , I also encountered this problem at work , I think, can be interpreted in two ways , first of , at maximum stress at a significant turning point in the model , there will be a singular point , it may be limited element analysis result , the specific I will not explain . Furthermore, we should consider the tensile stress and compressive stress , we know that the value of the compressive stress of the material received will be very high, is the material yield several times.
Can you attach your *.sldprt file and scanned hand calcs here?
