Hi Pipers,
I think I have got the answer , One thing that I am getting the zero stresses in case of rigids only that is correct. Other thing Can it happen the other way also? What I mean whether I can zero stress in non rigid elements also. If yes , then what case it may be and how to rectify it.
BOM i was checking the output stresses where I was getting the zero?
Cheers
