  Drop test, Informative value?

Good morning dear community,
I am currently working on the drop test studies at SW Simulation and have some questions.
An ABS housing is dropped from a height of one metre and hits the edge at an angle of 45°.

 

Actually, we want to assess whether it holds or breaks, or how it deforms. But how should one interpret the result?
Because the yield strength of the material is determined in the tensile test. According to my research, this takes about 1 minute. But in the case of an impact, you are more likely to be in the millisecond range and the material (in this case: ABS) will possibly withstand twice as much as the specified yield strength of 30N/mm².

 

I think the impact strength and elongation at break play a greater role here. But how do you incorporate this into the simulation? Check the element elongation?
How meaningful is such a drop test in SolidWorks?

 

I would be thankful if you could help me.
