Simply fix one end with all degrees of freedom. However, his question
is tricky if you are using solid elements. Due to the poison ratio you
may get a singularity right by the contraints. Therefore, stresses are
not good at the end where the contraints are apply but any stress away
from this location should be fairly good. Displacements, should be good
everywhere along the length. If you are using shell or beam
elements this problem goes away.
I just read your reply on ceaswaran's question. I am facing the same problem here. I have a simply supported chassis, and I am getting ridiculaously high stresses(singularity stress concentration) around the constraints. I am using all solid elements for my analysis. Is there a way to get away with that stress singularity? Should I just make a habbit of ignoring it, which is kind of questionable during presentations and stuff.
I've always had to use beam elements to get away from the singularities. There is a way to do it with solids if the shaft is overhung at all from the pivots/supports.
