After running a normal stress analysis, I noticed that thelocalstress was very high over 250,000 psi for a 36,000 psimaterial. In real life situaion the material would yeild anddistributethe stress.  In cosmos that is not the case, so Itriedrefining my mesh in that region, but that didn't seem to help.

My question is how is one to know when the local stress ishigh andshould be ignored when interpreting the results?

Also can anyone recomend a good basic FEA book or site thattalksabout this types of issues.
