dhengr,
FEA was performed and submitted the along with a similar hand calc. to the one that you described, only I used a circle rather than a rectangle for the assumption. The customer wanted to see the hand-calc for the ellipse specifically. Performed a buckling analysis using solidworks...
Basically yes. for some reason I am having a lot of trouble trying to find an equation to calculate the moment of inertia for an ellipse. I do need to take sheer into consideration as well.
Thanks
Can some one help me find the calculation to calculate the weld stress for a pipe attached to a plate at an angle. I cant seem to find a sheer calc for an ellipse. Please see the attached diagram
