I am not a Nastran user, but I'm working with someone who is. I'm an Ansys user. I'm accusomed to doing a plane stress analysis with PLANE42 elements. My co-worker is using QUAD4's with the out of plane degrees of freedom held. Is that valid? I thought a QUAD4 was a shell element, like an...
I'm not a Nastran user, but I'm looking at a plot of a Nastran model. It's using 2D plane stress elements. It appears that to go from a coarser to a finer mesh, there are corner nodes connected to midside nodes. I always thought that was wrong. Does it give good results?
I am looking for a reference with S-N curves for bolted joints. The joint we're considering would be like a diving board with a bolted support, so the bolts could see a prying action. Does anyone know of a good reference for those curves?
