Here is an example of the data I pulled for a 20lbs sledgehammer:

Mass | Strike Length | Strike Width | Total Length | Impact Velocity | Impact Area | Force | Kinetic Energy | Pressure 1 | |

F-International | 10.99961 | 0.08255 | 0.08255 | 0.9652 | 24.255476 | 0.0068145025 | 2668.007764 | 3235.689914 | 391519.0821 |

(That's all in metric)

I also have some datasheets on metal like this: http://www.postdiluvian.org/~mason/materials/steel_strength.html

or lumber like this: https://www.conradfp.com/pdf/ch4-Mechanical-Properties-of-Wood.pdf

And I used a formula I found for shear strength of metal: Force require = thickness * perimeter * shear strength of the material

However that came out with unrealistically high numbers:

Impact Area | Layer Thickness | Yield Strength | Tensile Strength | Force to Yield | Force to Shear |

0.3302 | 0.001 | 26000 | 47000 | 59192.8678 | 107002.4918 |

179263682 | 324053579 |

Any help would be appreciated!
