Shear Sheetmetal Force Equation and Calculator
Force required to shear sheetmetal equation and calculator
A shear force is applied that will cut off part of a sheet. The cut off ‘blank’ becomes the workpiece.
To find the shear force for a cut we can go back to the basic mechanics of materials (with one adjustment factor).
F = 0.7twUs
F = force needed to shear (lbf)
t = thickness of sheet (in)
w = width of sheet cut (in)
Us = Ultimate Shear Strength of material (lbs/in2)
