Reply To: Simulation of a Tensile Test to validate material properties

[henriquegpo]

Hello Armin,

Unfortunately I will have to put this project in standby for a while, but at least I have now a nice reference to read through.

I do have a couple of last questions I would like to ask though: despite this multiple necking issue that I see in my simulation, it should be OK to use that exact material model for analysis up to the necking stress/strain, right? Or does this also mean that my data is somehow "wrong"?

Also, from what you said about fitting with power-law or Voce function, I understood that I should only use data from the Yielding point to the necking, without any negative slope, just like the MISO model. Is that correct?

Thank you again for all the help and explanations, I really appreciate that!
