@18nanma: the short answer is: I have no idea. The long(er) answer is: you have to iterate on parameters within whatever you assume are reasonable bounds until the modeled behavior matches the experimentally observed behavior. This is often done by comparing macroscopic responses between simulation and experiment, with bounds of parameters informed by literature. Without literature values of the material you are interested in or a reasonable surrogate material, you are stuck either making big assumptions, or you have to go gather the data yourself (the latter being preferable). |

@18nanma The parameters you mention control plastic deformation (of metals). Does you material deform plastically? If so, it is actually what you want to model? |
