Stiffness of a curved plate

Stiffness of a curved plate

Stiffness of a curved plate

(OP)
I am doing a small analysis on a curved plate (like a pipe cut off in radial direction) designed to resist impact loads, but I have been unable to find the stiffness for such an element.

It is welded to support beams in one.

RE: Stiffness of a curved plate

You should treat it as an arc.
However, as you reference impact loads, if you have plastic deformation and eventually the collapse of the arc, then this is a problem that should be treated by tests.
