Impact Pressure/Energy for indentation

Impact Pressure/Energy for indentation

Impact Pressure/Energy for indentation

(OP)
I'm trying to find what pressure or energy would be required to indent copper by 1mm.  To be more specific it would be for a piece of copper sheet that was about 1mm thick and resting on some dust like particles so nothing too hard underneath.  It would be struck by a pin like object that had a rounded end of about 1mm diameter.

If anyone could help with what the best way to calculate this would be it would be much appreciated.

Thanks.

RE: Impact Pressure/Energy for indentation

If you can specify the shape and the dimensions of the indenter you want to use, you might be able to set up a simple test with any hardness testing machine, setting the support as you wish.
Note that different tempers of copper may give different results.

This is a tough question to me. The result worths a paper.
