Hallo Mr Wenlong, If you are willing can you help me? I really appreciate your help. I want to carry out a tensile test simulation with AISI 4140 material, actually I don't know the correct tensile test simulation process. Is there a video that you suggest or a discussion that I can learn from to carry out a tensile test simulation? 

For the tensile test, does the Explicit Dynamic option use "Force" or "Displacement"? 

And I want to ask if to fill in the force data, how many values do I need to input?
Thank you very much all.
