Hi!

I am trying to perform a tensile test on a specimen that consists of 2 sheet of steel, connected with one spot weld, placed in the center od the contact area, image below

 

The results I'm getting are far from reality, as I performed the test irl too. 

Are there some features that need to be added to the Mechanical simulation?

Let me know if you need additional information from me

I am using Explicit Dynamics, fixed support on one side, and on the other:

• Force - ramped by tabular data - resulting in kind of correct stress, but way too small displacement in Z direction for a force that is not even close to the real one, or weird deformations for force closer to the real one.
• or Displacemet - I input the displacemet that the irl specimen achieved, but the only thing that is getting displaced is the very side that the displacemet is attached to, like below.

Hi, do you know how quickly load is applied? The reason I ask is explicit would be appropriate choice if load is applied very quickly, ideally within a fraction of seconds, is it the scenario that you are testing?
