5. RIVETED JOINTS
A riveted joint is a permanent joint
which uses rivets to fasten two
materials.
Structure that has a hemispherical head
on one side and a cylindrical shaft on
other .
One installation the rivet is placed in a
punched or drilled hole and tail is upset
or bucked (i.e. deformed) show that it
expands to about 1.5 times the original
shaft diameter, holding the rivet in
place. 5

6. Important terms used in riveted joints:
1.Pitch: The distance from one rivet center to another
rivet center.Denoted by p.
2.Back pitch: The perpendicular distance between the
center lines of the successive rows.Denoted by 𝑝 𝑏.
3.Diagonal pitch: The distance between the center of
the rivets in adjacent rows of zig-zag riveted joint.
Denoted by 𝑝 𝑑.
4.Marginal pitch: The distance between the center
of the rivet hole to the nearest edge of the plate.
Denoted by m.

7. Lap Joint :
A lap joint is that in which one plate
overlaps the other and the two plates are
then riveted together.
Butt Joint :
A butt joint is that in which the main plates
are kept in alignment butting (i.e. touching)
each other and a cover plate (i.e. strap) is
placed either on one side or on both sides
of the main plates . The cover plates is then
riveted together with the main plates.
TYPES OF RIVETED JOINTS

8. SINGLE RIVETD JOINT:
One rivet is fixed along a single raw
typically in a lap joint , while in a butt
joint the rows may appear from both
the upper and the lower surfaces .

DOUBLE RIVETD JOINT:
When two rows of rivets are included
over a lap joint or when two rivets are
utilized from both top & bottom in a
butt joint are referred to as double butt
joint.

10. 10
CHAIN RIVETED JOINT :
In this type the accommodated rows of
rivets may lie exactly opposite to each
other over straight lines .

ZIG ZAG RIVETED JOINT :
Unlike the above type, here the rows
may appear staggered and not
complementing each other.

1.It is used where we have to avoid after thermal effect as in case of
welding .
2.Used for metals which have poor weldability.
3.Used for heterogeneous materials like asbestos friction lining and
steel.
4.As welded joint have poor vibration damping capabilities so where
required rivet are used in place of it.
5.Used for aircraft structure where aluminum is used.
Application of riveted joint:

ADVANTAGES OF RIVETED JOINT:
1.It is a more reliable.
2.It can also be used for non ferrous metals.
3.Parts assembled by riveted joint do not have any thermal
after effects.
4.Its quality inspection is easy & cheap.
5.When parts are dismantled riveted have less damage
compared to welded parts.
DISADVANTAGES OF RIVETED JOINT:
1.Due to holes plates become weak.
2.Overall cost of riveted joint is more.
3.They have more weight than welded joint.
4.Stress concentration near holes.

15. Failure of riveted joints
15
Shear failure.
Tensile failure of plates
Crushing failure of plates
Shear failure of plates in marginal area
Tearing of plates in marginal area
Bearing failure of plates
Shearing failure of plates
