It is important to check a FEA solution in several ways. Does the deflection look correct to you? Do the reaction forces make sense? Do the stress values change with a finer mesh? Is there a smooth gradient in the stresses? The difficulty in using xpress is that the tools needed to interrogate...

The oring will be pressurized at 2500 psi through the crossection. You could think of the oring as being a high viscosity liquid. The backside of the oring will have a pressure of 2500 psi pressing on the wall which is supporting the oring. The oring has very little strength. The pressure of...

Buy a set of Bose noise cancelling headphones ($300) and a CD player. I listen to classical music, mild south american guitar, smooth rock. The headphones cut the noise level down enough that the music can overcome it completely.This setup saved my career.

I believe a stress concentration multiplier should not be applied to a FEA result in a radius. (assuming a fine mesh) The question I would pose regards the depth of the stress. If the stress decreases by 30 %, .010" below the surface in a 4" shaft, .25" R, I wonder which stress to use.

It always good to use fem if you have he software and are quick with it. If the geometry is complex; beyond a cube or a cylinder FEM forces you to state the problem and think it through. Many engineers that I have seen, who do not do FEM, do not do free body diagrams or many pages of hand...

Typically, I don't have time for runs to check for convergence. I check the "energy norm error." (the difference between nodal and elemental stresses) My usual practice is to refine the mesh, with mesh controls, finer and finer until the meshing and run time slows. "Finer the better" with H...

The first thing I would look at would be the displacement plot deformed. The animate it . Does the movement make sense? The displacement plot can show poor constraints. Finite Element Analysis is faster and more accurate than handbook methods. CosmosWorks and SolidWorks are easy to use...
