rivet

[stinsondawg]

Is there a standard or any guidelines as to how many layers of material a rivet can fasten together? Typcially I see a rivet fastening two or three layers of material together. I have a design that currently passes a rivet through 4 pcs of material.

The structure is an all aluminum housing, it is not a pressure vessle. The design is such that in a couple of areas I have a rivet passing through a mounting flange, stiffener plate, housing, and then an internal bracket. Am I asking too much of that rivet?

Any help, suggestions, or guidelines would be appreciated

No standard nor guideline that I know. I don't think you are asking too much of the rivet. Just design it well - hole size (and tolerance), clamp length (and tolerance), and surface pressure (formed head and the back side), among others.

Thanks for your feedback. I think I have a pretty solid design, only four of many rivets pass through 4 layers.

Stinsondawg,
Check out the section on rivets in Machinery's Handbook. Several formulas and tables dealing with the information you are seeking.
