Not scientific at all but figured I'd share.
Ace hi-speed broadhead torture test 100gr. broadhead was sharpened and stropped, easily cut hairs prior to testing. First test arrow flew exactly like my field tips. second test I shot it into that fiberglass renforced plywood board, Then I shot it into a very thick piece of bamboo. It penetrated but twisted the tip. 4th picture you can see why the head came in and cut very cleanly on a Horizontally angle which is quite impressive. As it cut through the bamboo started to split which caused the head to twist vertically (can see the cuts in the bamboo as the angle of cut goes to vertical) Very last test with twisted tip was into a steel belted tread of a tire which as you can see it penetrated slightly then the rest of the head folded over from the pushing force behind. If you look close you can see the bend is only from the tip that that extra steel doesn't come up to. If this were the ace standard head which is triple laminated at the tip I bet it would still be good. Still quite impressive for a 100gr head.
