Hello everyone, I have this problem which always bother me a lot! whenever I do FEA on any part and compare the results against the hand calculations what I notice is huge anomaly which is clearly not in the range of 0 to 15% of FEA results. I have even showed those calculations to my supervisors which they think are correct but I just can't understand the reason for such deviation! Has it happened to anyone else? What is the solution for this?
