Hello, I run two similar NASTRAN solid composite elements models with sol 400 and LNSTATICS and I obtain different stress results. Why is that? Below are details about the models
The only difference between the two models is that for one, I specify a failure model thanks to "MATF" and ask for the strength ratios with "PARAM,SRCOMPS,YES".
Doing that, I obtain a 40% higher stress.
I have made sure that SR>>1 so that progressive failure or yielding can't be the cause of that.
I also compared the files to ensure the mentioned differences were the only one.
MATF properties are only for failure, how do they affect the results when failure is not reached? I understand the results may not be good with PCOMPLS L but at least shouldn't they be consistent?
