Hi all,
I have a problem when I try to make a nonlinear static analysis on Femap using a temperature-dependent function to represent the yield of the material.
I'm using the yield criterion from Von Mises, selecting in extended material model the function "Yield vs Temperature" which I defined previously.
I get, among others, the error no. 4676. I don't know how to do in order to introduce the "Yield vs Temperature" function properly in the Von Mises Yield Criterion in the "Non Linear Options" of the material. It seems as if the Nastran doesn't recognize this temperature dependence of the Yield.
I've searched in femap's help file and I've found this note:
"The "Initial Yield Stress" in the Define Nonlinear Material dialog box must be set to "1.0" for this to work properly when using this to define temperature dependent materials with a "5..Function vs. Temp" function. "
I've tried to do this point but I still doesn't work. I don't know what is going wrong.
I upload the model file and the *.f06 file.
Lots of thanks,
Alberto Souto
