Hello,
I am analysing a tubular-frame chassis collision using the explicit dynamics solver on Ansys.
I have sufficient data regardign the 3140 steel properties as you would expect. However I want to explore the deformation and I want to allow the structure to deform to try and give a best possible simulation result.
Aside from the density, Youngs modulus, Tensile and Yield strength what should I bring in to explore the plasticity characteristics. From what I have seen, I need to define the material surface finish, and either the Johnsons cook strength, multi-linear or bi-linear isotropic characterstics. Is this true.
I understand for things such as johnsons cook strength requires testing. Could someone please advise me on this and what would be the best approcah to take.
Thank you
Ryan
