Single Solid Element Testing

Altair Forum User

Hi George, 

 

I try to do a single solid element experiment to test out different material properties, ect. However, I struggle to setup the experiment boundary conditions. When I use a setup where I fix the lower nodes in all 6DOF and apply a force on the top ones (see the image) than I restrict the lower nodes and prevent them from any lateral contraction. On the other hand, when I setup my experiment as a beam-experiment I have no possibility to measure the diameter and see if it contracted as expected. 

What is the best way to go?

 

Thanks, J

Hi Jonas,

You may just try with both approaches and see the results. If they are close enough I think you can go ahead with solid element.

I tried with the solid element. The problem is when my turn my passions value up (from 0.3 to 0.4) than my solid behaves wired (see iamge). I wanted to check if this is an issue due to the fixation or a general problem. 

 

Thanks, J

Hi Jonas,

This could be due to the material characteristics. Also, you can try the same with different solid element (Isolid) formulation and review the outcome.
