A correlation relating nondimensional macroscopic thermal resistance to the geometric variables of a bolted joint has been developed. The variables considered include the upper and lower plate thickness, the plate radius, the contact zone radius, and the bolt radius. Experiments were conducted using an electrolytic analog method. The investigation was conducted over a range of variables that include the plate thicknesses, 0.95 to 2.22 cm; the bolt radii, 0.32 to 1.27 cm; the plate radii, 5.1 to 10.2 cm; and the contact zone radii, 1.27 to 8.89 cm. A numerical technique was developed that accurately predicted the experimental results to within ±8 percent. Based on the analysis and experimental data, a correlation was developed that may be used to predict the macroscopic thermal resistance in bolted joints.
