# Punching and blanking force
# Scope: Uniform shearing perimeter with supplied material shear strength.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

perimeter = 100 mm
thickness = 1 mm
shearStrength = 250 MPa

force := perimeter*thickness*shearStrength [kN]

check punch force budget: force <= 30 kN

scenario alternative: perimeter = 80 mm
