I need to calculate the force of a pin impacting a solid metal. I know the shape of the indenter, the precise shape and depth of the indentation and the mechanical properties of the solid metal including modulus, yield and ultimate strength. The pin is being driven by ultrasonic wave guide so it is not simply a gravity problem.(adsbygoogle = window.adsbygoogle || []).push({});

In my mind this is the basic equation that Rockwell Hardness uses with the exception that they know the force and indenter shape and measure the depth of indentation to calculate hardness.

Does anyone know how to solve this?

Thanks
