CELAS1 element set as strain gause

MartinaC

Hi everyone,

I am simulating a tensile test with Optistruct. The analysis is NLQS and the material is isotropic.

 

I set the analysis as proposed in the eBook 'Introduction of Non linear finite element analysis using Optistruct', section 3.1.5 Tutorial: Small-Strain and Large-Strain Plasticity in a Test Coupon.

 

I would like to understand how to set the CELAS1 element in order to use it for the building of the force-displacement output curve. I created the element, but the output curve results flat, so I think the problem is the Set.

 

Attached is the .fem file, is usefull.

There are other possibilities to simulate tensile tests of non homogeneous coupon bars and export the global stress-strain curve? Because I am able to export just the stress-strain curve of each element
