While performing Dynamic analysis on a Chassis (made of AISI 4130 Chromoly Steel), when assigning the material what should we select for type and card image option?

Confused on which type of material and which card image to choose

Hi,

 

it would be nice if you take a look at the Radioss documentation for a better understanding of what material models Radioss supports. All these different types should be there.

 

But usually, for a elasto-plastic material, you would use MAT2 or MAT36.

MAT2 uses the JohnsonCook equation/parameters for building the plastic curve.

MAT36 can be used if you have the actual plastic curve (stress-strain).

 

If you're new to explicit simulations, I suggest you to go through the Radioss e-book, first:
