The buckling analysis was a good idea. However, I ran that, and found my current load is NOT bigger than the eigen buckling limit. I was hoping that would be the case.
I did do runs with less load and found that my solution converges. kellnerp, what do you mean by "collapse."? Is that something...
I have a side project, where I am supposed to model a surf board in 3D, which entails that I need to model the core in 3D also. Correct me if im wrong, but I dont think Hypermesh has the ability to do 3D orthotropic elements. Does anyone have any suggestions on how to model core in 3D using 2D...
Thanks for all the great comments. In response to the last posts:
ThomasH,
I dont have any yield limits in the model. I have linear isotropic & orthrotropic materials in the model, so it shouldnt recognize yields.
EricZhao,
Ive already thought about that. I did a test where i imposed 2 of the...
I dont have any rbe2 or bars. I tried increasing the NLPARM card several times, but my model still seems to converge at about 90% of load, and then diverges. Maybe my part is too flexible like you mentioned, which means i should stiffen it.
There was a previous thread similar to this which I read, but in didnt prove helpful. So here I go posting this thread, hopeful that someone has run into a similar situation.
I am running SOL 106 for a beam-column type of analysis, nonlinearity for the displacements. The constraint is simply...
