Reply To: Radial displacement, hoop and meridional stress of dome

[nm20004]

Thanks Clarkt for your reply! I created a named selection of the ply in which I want to calculate the meridional and hoop stresses. Then for this named selection I created the element orientations with x axis in the meridional direction and y axis in the longitudinal direction.

Then, I inserted in the solution branch stress->membrane stress. And for the named selection of the ply of my composite I created, I calculated hoop stresses in the local element direction 22 and meridional stresses in the local element direction 11. But the results are not uniform. For example hoop stresses have this kind of distribution.

Do you think that my method is correct, or this ununiform distribution could be caused due to bad mesh or bad definition of the variation of winding angle of the fibers along the dome? If my method is not correct could you please help me?
