Formula and methodology
Formula: Required diameter d = √[4 × design load × safety factor/(π × rivet count × shear planes × allowable shear stress)].
The model distributes a stated shear load equally over circular rivet shear areas and reports a theoretical minimum diameter before practical detailing.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Design shear load — N; minimum 1.0E-6; maximum 1000000000000
- Rivet count — minimum 1; maximum 1000000
- Shear planes per rivet — 2 choices
- Allowable shear stress — MPa; minimum 1.0E-6; maximum 1000000
- Planning safety factor — minimum 1.0E-6; maximum 100
Worked example
| Input | Value |
|---|---|
| Design shear load | 12000 |
| Rivet count | 4 |
| Shear planes per rivet | single |
| Allowable shear stress | 120 |
| Planning safety factor | 1.5 |
Theoretical required rivet diameter ≈ 6.91 mm.
Assumptions and limits
- The load is shared equally and the stated allowable shear stress is converted from MPa to Pa.
- The selected single- or double-shear plane count represents the intended idealized failure plane.
- Bearing, tear-out, net-section tension, eccentricity, fatigue, hole clearance, installation quality, and code design are not modeled.
