PLATE DEFLECTIONS IN SIMULATION
PLATE DEFLECTIONS IN SIMULATION
(OP)
I am analyzing the top of a 144" long, 36" wide, and 10 gage thick rectangular steel tank as shown in the attached sketch. There are 2-1/2" deep by 34" long stiffeners evenly spaced and welded to the underside of the plate. The edge restraints prevent vertical movement and movement parallel to the edge, but allow movement perpendicular to the edge. The top plate is loaded with a 3 psi upward load. The results show much larger stresses and deflections between the last stiffener and the restrained end of the plate. This does not make sense, but I do not know what the problem is.
Any thoughts?
Any thoughts?






RE: PLATE DEFLECTIONS IN SIMULATION
Have you checked to see that you really have the same loads on each panel?
Have you checked to see that your mesh does not have two elements occupying the same location?
Have you checked to see that you haven't doubled up on the loads on that panel?
Just some thoughts.
