material properties for impact analysis

[Breezer]

I am doing an impact simulation on an electronic housing. The material is an injection molding ASA grade with enhanced toughness and heat resistance.

Any recommendations regarding material properties required for this analysis?

Additional to the usual, Young’s Modulus, Poisson’s Ratio, Density and Yield Stress, I suppose, Tensile Curve and Hardening Modulus.

Which hardening rule and yield model would you suggest?
Would you take strain rate sensitivity into account?

Thanks for your input.
