Design Considerations
Rivet Selection Guidelines:
- Material Compatibility: Match rivet material to base material
- Diameter: Typically 3-4 times sheet thickness
- Length: Grip length + 1.5 x diameter for upset
- Spacing: Minimum 3 x diameter center-to-center
- Edge Distance: Minimum 2 x diameter from edge
Joint Strength:
- Shear strength proportional to rivet cross-sectional area
- Bearing strength depends on sheet thickness and rivet diameter
- Multiple rivet patterns distribute load
- Consider fatigue loading in dynamic applications
