WebMar 1, 2024 · The punch force required to produce a 3 mm hole in 5 mm thick stainless steel is 18.84 kN. First, we calculate the perimeter of the hole using its diameter, π × 3 = 9.42 … WebThe physics. Basic physics tells us that punch force is dependent on the Impulse-Momentum relationship (the change in momentum experienced by a body under the action of a force is equal to the impulse of the resultant force). If you have more mass (weight) and you can move that mass quickly (momentum) you’ll create more impulse on your target.
