William A. Nash defines shear force thus: "If a plane is passed through a body, a force acting along this plane is called shear force or shearing force.[1]
Shear force of steel and bolts
Here follows a short example of how to work out the shear force of a piece of steel. The factor of 0.6 used to change from tensile to shear force could vary from 0.58 - 0.62 and will depend on application.
Steel called EN8 bright has a MPa of 800 and Mild steel has a MPa of 400.
To work out the force to shear a 25mm diameter round steel EN8 bright;
Area of the 25mm round steel in mm2 = 12.52*π = 490.8 mm2 0.8kN/mm2 x 490.8mm2 = 392.64kN = 40 ton X0.6 (to change force from tensile to shear) = 24 ton
When working with a bolted joint, the strength comes from friction between the materials bolted together. Bolts are correctly torqued to maintain the friction. The shear force only becomes relevant when the bolts are not torqued.
A bolt with property class 12.9 has a tensile strength of 1200MPa (1MPa = 1N/mm2)or 1.2kN/mm2 and the Proof Load is 900MPa = 0.9kN/mm2
A bolt with property class 4.6 has a tensile strength of 400MPa (1MPa = 1N/mm2)or 0.4kN/mm2 and the Proof Load is 600MPa = 0.6kN/mm2
