A riveted joint may fail in the following ways
1. Tension failure in the plates
2. Shearing failure across one or more planes and shearing failure of the rivet
3. Bring failure between the plates and the rivets.
Hence the option D is correct.

Introduction:
A riveted joint is a type of mechanical joint used to connect two or more components together. It consists of a rivet, which is a cylindrical metal pin, and two plates that are joined together by the rivet. The rivet is inserted through holes in the plates and then deformed to form a permanent connection. However, under certain conditions, a riveted joint can fail.
Explanation:
A riveted joint can fail due to a variety of reasons, including tearing of the plate, shearing of the rivet, or bearing of the plate or rivet. Let's discuss each of these failure modes in detail:
1. Tearing of the plate:
- When a load is applied to a riveted joint, the plates experience tensile forces that can cause them to tear.
- This can occur if the plates are not properly designed or if the applied load exceeds their tensile strength.
- Tearing of the plate can lead to the complete separation of the joint, resulting in joint failure.
2. Shearing of the rivet:
- The rivet in a riveted joint can also fail due to shearing forces.
- Shearing occurs when the applied load is perpendicular to the axis of the rivet, causing it to shear off.
- This can happen if the rivet is not strong enough to withstand the applied load or if there is excessive play between the plates and the rivet.
3. Bearing of the plate or rivet:
- Bearing failure occurs when the contact pressure between the plate and the rivet is too high, causing the material to deform or fracture.
- This can happen if the rivet diameter is too small or if there are sharp corners or edges on the plates that concentrate the load.
- Bearing failure can result in the loosening or disintegration of the joint.
Conclusion:
In summary, a riveted joint can fail due to tearing of the plate, shearing of the rivet, or bearing of the plate or rivet. All of these failure modes can lead to the complete failure of the joint. Therefore, the correct answer to the question is option 'D' - any of the above. It is important to properly design and analyze riveted joints to ensure their strength and reliability in various applications.
