Over Driving of Rivets
Over Driving of Rivets
(OP)
Hi,
I have a two layered skin panel. One layer is 0.200" inch thick and the other layer is 0.050" thick.
BACR15FV8KE(*) rivet will be installed in this panel. Head will be on the thicker panel side and tail on the 0.050" thick panel.
Is there is a minimum skin thickness requirement regarding overdriving of the FV rivet? Can the buck tail be over driven to 1.5D or this will damage the 0.050" thickness panel in the process?
Thanking everyone in advance for their response.

The thin sheet may circumferentially buckle around he rivet as a result of rivet-shank interference and tail compression stresses.
NOTE.
1/4D KE rivets have very high driving forces and are a pain to set without squeeze tooling.
NOTE.
Cherry recommends minimum blind-side sheet thicknesses and alloy/tempers for its high strength blind rivets... because the bulb formation depends on the yield strength/stiffness of the back-side sheet hole-lip.
