You can't. GURPS isn't granular enough, nor suited to the complex and highly variable maths involved. It's done by GM fiat. The closest you get is Breaking Blow, but that specifically requires the object to be braced.

So, again, it just comes down to GM fiat, which can be as realistic or not as the GM prefers.
