I really hope someone can help. I have spent the last week several hours a day trying to get this answer via Google. I am doing research on the practical difference between a mace and axe in combat. Strangely enough there's almost nothing concerning the techniques of using a mace in period manuscripts. At least not any translated to english. I have most of my answers from physical testing and my 30 years of real life tournament fighting. But the one problem I am having is trying to get a straight forward answer. A formula to find the concentration of force from a blunt "hammer" head of 1x1 inches to a blade 0.1 x 2 inches (not sharp as melee weapons get dull fast in armored combat) . What I really want to know is how much more deformation will occur to a plate of steel from the mace to the axe. A "modifier" to be use on a mace that say does 30 pts deformation damage but that same mace reshaped into an axe (same ballance, length, weight etcetera) would do X amount more of deformation damage. It can be simplified as this is for programming a game not anything important and needs to be written out like 2.0 x (weight x 0.5) / sqr) or similar to that. Thanks and sorry for such a frivolous question, but I am stumped on this other than to think it is just a logical answer like factor = (1.0 x 1.0 ) / (0.1 x 2.0) . I feel it cannot be that easy based on the other formulas I have researched such as the fact that the length of a hammer handle is a quadrilateral factor not a liner one.
