Trying out a simple model in Nastran. Basically intent is to demonstrate geometric non-linear effects on a wire subjected to transverse load. The wire is hinged in both sides. I want to capture the membrane stiffening effects due to geometric non-linearity. Initially, I was modeling using CROD but the 106 analysis failed to run. I need to re-read the Non-linear guide, but I think 106 does not support PROD/CROD in 106 solution?
Then tried CBEAM and I was able to run the analysis correctly. Anyways, was curious to find out if I can do a better setup than the above. Perhaps using a different element which can capture wire physics more accurately in non-linear. Would CGAP might be a better option? Not sure if Gap elements are effective against transverse loads.
I intend to do a better research on the above coming weekend. Anyways, posting here to get a flavor from folks with experience in non-linear analysis.
