A force of 1100 KN is applied to punch a 40-mm-diameter hole in a plate. If the shear strength is limited to 700 MPa then what thickness of the plate is required?
In a sheet metal of 2 mm thickness a hole of 10 mm
diameter needs to be punched. The yield strength in
tension of the sheet material is 100 MPa and its ultimate
shear is 80 MPa. Calculate the force required to punch the hole (in
kN).
A hole with a diameter of 18 mm will be drilled in a sheet material with a thickness of 4 mm. Calculate the shear force in kN since Rm=640 MPa for sheet material
