Once calculated, you can compare this with an unperforated plate's strength and determine efficiency by dividing one by the other.
The formulas for calculating the strength vary based on loading and joint type, but they involve finding the minimum value among possible modes of failure: shearing of rivets due to shear stress exceeding their material's strength tearing of plate due to tensile stress exceeding its material's strength and crushing due to bearing stress exceeding either material's bearing strength. Additionally, you must be aware of the shear strength of the rivet material, τ the tensile strength of the plate material, σ and the bearing strength of either material, c. To calculate the strength, you need to know the nominal diameter of the rivet, d the pitch, p the gauge, g the thickness, t and the width, w of the plate as well as the number of rows and rivets in each row. USE OF RIVETS Riveted joints are permanent fastenings and riveting is one of the commonly used method of producing rigid and permanent joints. Single riveted lap joint:- A lap joint in which only one row of rivet is used is known as. There are following types of Lap Joint- I.
The jointing of members are done by using one row of rivet or more than one row of rivet.
The strength of a riveted joint is the maximum load it can carry without failing, depending on the type of loading (tensile or shear) and the type of joint (lap or butt). 11.Types of Rivet Joints Riveted joints are following types:- i) Lap joint ii) Butt joint Lap joint:- In lap joint the members are connected together by overlapping.
