Simply Supported Plate - Bending in transverse direction
Simply Supported Plate - Bending in transverse direction
(OP)
I have noticed when modelling a simply supported plate in an FE package, I am getting moment actions transverse to the main span. (I am just testing the software).
When the deformed shape is checked, the free edges deflect slightly more than at the midspan, which is consistent with some form of transverse action occurring.
Why is this occurring, considering the plate is spanning one-way?
I am using a finely meshed quad element mesh.

This is due to the Poisson ratio and the lateral contraction connected to it.

I didn't factor in poisson's effect.
How relevant is this effect? I guarantee 90% of design engineers would never factor this in ("a slab spanning one way spans one way!!").

I guess that anyone would consider these differences as negligible; more importantly the beam behavior gives a higher stress and is therefore on safe side.
But you raised a question and got the answer...
