I am modelling using Abaqus a concrete block with FRP sheets on its top and bottom the FRP sheets are pulled by a point load at the centre the connection between FRP and block is tie the stresses on the bottom should be like the bottom but they are not.
Hi Mohammed Shehadah,
Deformed shape will help you to see all symmetries and non-symmetries. I think that both sheets should be deformed symmetrically, but each sheet is not only stretched but also bended.
The supports are symmetric and the deformed shape is symmetric but the problem is in stresses
Dear Mohammed,
More info is needed. Some times this problem happen in Explicit analysis if you used. attached another fig with u2 contour.
I am using static general analysis the u contours are symmetric the problem is in the stresses and damage
Please rotate this fig 180o around z axis to see bottom surfaces.
Although it may cost you, but I think it is similar to your project, so check the link:
