Static versus dynamic (impact) load

[nestorphi]

Hello Everybody,

I am trying to analyse a composite tube impacted by a certain mass (22 kg) drop at a height of 3 m (velocity = 7.7 m/s)using Strand7 nonlinear transient dynamic solver. I need to find out the dynamic load to be applied on the tube. Are there mathematical equations that define the relationship between the static load (m x g) to the dynamic load (drop at a height of 3 m)?. Obviously, dynamic load should be higher than the static load. In my experiment, the dynamic load is 33 times higher than the static load when impacted by 22 kg at 3 m height.

I appreciate your help.

Regards to all and thanks lot.

It depends on the materials involved and the impact time. The shorter the impact time, the higher the acceleration. Conservation of energy
