Stress Strain values of 0 for Non-Linear analysis

Post by sm3082 »

I am trying to complete non linear analysis for a structure and have defined material properties using the el_mat, but always get 0 as the stress and strain values. What am I doing wrong?

Thanks

Hello sm3082,

Indeed there is a problem in the el_mat material model and the stress point values are not exported correctly. We will fix this in the next release of the program. Many thanks for reporting this.

Note that you can also monitor the stress-strain state of the cross-section with the stress and strain peaks output. In order to activate this you should go to the Output page of the pre-processor and select the elements for this output (by default the stress and strain peaks and output for no element).
