Splitting Metal

Splitting Metal

Splitting Metal

(OP)
I'm trying to Figure how to calculate the force needed to be applied to a wedge to split a piece of metal. The metal would be sitting on a flat surface and not constrained in any way (other than the surface it is sitting on) and the wedge would be coming straight down on it. The piece of metal would be a a rectangular prim, and the wedge would be going across the smaller cross-sectional area. I have seen similar threads to this but i didn't see any straight answers come from them.

RE: Splitting Metal

How thick??
What material??

They make shears that are designed specifically to do this. Or send it out to fab shop to perform the work??

RE: Splitting Metal

(OP)
I would like to come up with and equation so i could calculate the force for any thickness (the wedge will always be wider than the material being cut), and the material would grade 8 steel.

RE: Splitting Metal

The resulting 'split' edges (and adjacent faces) would be a mess. What is the purpose of splitting the material in such a manner.

RE: Splitting Metal

There is no simple equation that can be used for this. Plastic deformation and fracture are complicated mechanisms that cannot be simply defined, because there are too many interacting variables.

I figured as much I'm looking more for like a ball park figures, but I may have come up with something today that will work for me.

Thanks for responding guys.

It's probably going to be wrong.

Speed , Temperature. Alloy, HT, etc., etc., etc.

Screwman1,

Don't forget grain direction, wrought/forged/cast, surface discontinuities, etc.

RE: Splitting Metal

At any rate, a very large ballpark:)
