Hello all,(adsbygoogle = window.adsbygoogle || []).push({});

I've been trying to model a plate under uniform tension using FEA techniques (in ANSYS). The plate has a circular hole in the centre, and has two axes of symmetry so I've created a mesh based upon the 'top right' quarter of the plate.

I'm pretty sure I've done everything right, the mesh looks good, my boundary conditions are sound, I think it's all good. I've constrained the base, and applied a static load to the 'top' edge. I'm solving for the local stresses (in X and Y directions) in the plate.

However, when I've run the simulation and obtained my values (which do appear to be in the right ball-park), my answers become further away from the exact solution the more I refine the mesh. I can't understand this!

In all fairness I'm really not up to speed with my FEA, any help would be a big bonus!

Cheers.
