2. WHAT IS RIVET?
 A rivet is a round rod of circular cross-
section. It consists of two parts HEAD and
SHANK.

SHAN
K
TAIL
Metals commonly used for rivets are Mild
steel, wrought iron, copper and aluminium

3. WHAT IS RIVETING
 Riveting is the process of forming a riveted
joint. For this, a rivet is first placed in the hole
drilled through the two parts to be joined.
Then the shank end is made into a rivet head
by applying pressure

4. PROCESS OF RIVETING

5. USE OF RIVETS
 Riveted joints are permanent fastenings
and riveting is one of the commonly used
method of producing rigid and permanent
joints. Manufacture of boilers, storage
tanks etc.
 These joints are also used to fasten rolled
steel sections in structural works, such as
bridge and roof trusses.

9. TYPES OF RIVETED JOINTS
 There are two types of riveted joints.
 1. RIVETED LAP JOINT
 2. RIVETED BUTT JOINT

12. CASES OF FAILURE OF RIVETS
 Under Tensile Stress or Tearing
resistance of plate per pitch.
P(t) = (p-d) x t x
o
σ(t) resistance of plate per pitch.
Where,
P = Tearing
o p = Pitch
o t = Thickness of plate.
o σ(t) = Permissible tearing strength.

13. CASES OF FAILURE OF RIVETS
 Under Shearing resistance of plate per
pitch. 1
P(s) = n{ } xor
2… (/4)d2 x
or
ζ(s)
1.875
Where,
 P(s) = Shearing resistance of plate per
pitch.
 d = diameter of rivet hole
 ζ(s) = Permissible shearing strength.

14. CASES OF FAILURE OF RIVETS
 Under Crushing resistance of plate per
pitch.
P(c) = (nd) x t x
σ
Where, (c)
 P = Tearing resistance of plate per pitch.
 n = Number of rows of rivet.
t = Thickness of plate.
 σ(c) = Permissible crushing strength.

15. EFFICIENCY OF RIVETED JOINT
Least value of
η P(t), P(s), of(c)
Strength P un-riveted
= plate
Where,
 Strength of un-riveted plate = σ(t)pt
