Formula : d = 6.04 × √t
Where,
d = Nominal Diameter of Rivet in mm
t = Thickness of Plate in mm.
The Unwin formula is used to determine the size of the rivet. Unwin's formula gives a relation between hole diameter of rivet and thickness of the connected plates. The 'd' in the formula represents nominal diameter of the rivet in millimeters (mm) and 't' represents thickness of the plate in millimeters

Unwin formula for Rivet Diameter Calculation

The Unwin formula is used to calculate the diameter of a rivet for a plate of thickness t.

Formula: d = 6.04 x √t

Where,
d = diameter of rivet
t = thickness of plate

Explanation

The Unwin formula is based on the shear stress that is required to shear the rivet. The formula states that the diameter of the rivet is directly proportional to the square root of the thickness of the plate.

The coefficient 6.04 is used because it is the ratio of the maximum shear stress that a rivet can handle to the yield strength of the material of the plate. The formula assumes that the plate material is ductile and that the rivet material is stronger than the plate material.

The formula is widely used in engineering and construction applications where rivets are used to join two or more plates together. The formula ensures that the rivet is strong enough to hold the plates together, without being too large or too small.

Conclusion

The Unwin formula is an important tool for engineers and construction experts to calculate the diameter of a rivet. The formula ensures that the rivet is strong enough to hold the plates together while also being of an appropriate size.
