Worked example

Inputs

Cut perimeter: 100 mm
Sheet thickness: 2 mm
Material shear strength: 250 N/mm²
Effective penetration fraction: 0.3

Expected results

Nominal peak shearing force: 50000 N
Constant-force cutting-work estimate: 30 J

How to use this tool

Enter every input in the labeled units; use measured or independently specified properties.
Check the stated model assumptions before calculating.
Interpret the output as a model estimate and verify it independently for the intended application.

Try this example

{
  "perimeter": 100,
  "thickness": 2,
  "shear": 250,
  "penetration": 0.3
}

Accuracy and scope

Nominal estimate; actual force curve, clearance, stripping, tool shear and press dynamic capacity are not modeled. Educational engineering estimate only; not structural or safety certification, equipment selection, or operating recommendations.
