plug under impact

[gtsolid]

Hello, everyone.
imagine a rotating steel cylinder having a protrusion.
it goes down at a certain speed against a cylindrical plug (rolling at 1600 mpa).
How do I size the shock plug?
I know the kinetic energy of the cylinder.
I hypothesized a shock time of 4ms. This way I could quantify the barrel, but I'm not sure. Do you have ideas?

if wrong mortgage you will have a wrong application.
I imagine this tree has a safety plug that you have to pull if it exceeds a certain strength, couple, energy. Right?
if you calculate kinetic and potential energy that turns into non-elastic shock energy but not 100%, if you do a throat in the safety plug, if the cutting formula is f=4/3 t/a ....admitted that I have to do the theory of carving because it is not true the previous theoretical formula, if the material has an elongation different from classic 20% and therefore the engineering break load is not all real.
then if you don't need security, think about a leaner alternative.

Actually, it's a fine safety rush. You don't have to quit.

If you have to make calculations, the result is wrong.
on many types of steel charpy pendulum has very different results between summer and winter, figure between steel and steel.

Even worse. because if it is a safety limit must be safe and therefore dimensioned right.

size to the eye, and then put two.
