One of the parameters needed to calculate the thermal contact resistance across a bolted joint is the interface pressure distribution between the plates of the joint [1, 2]. As part of a study [3] on thermal joint conductance, a three-dimensional photoelastic analysis using the stress freezing technique was used to predict the interface pressure. Nine bolted joint geometries were investigated using smooth flat plates of photoelastic material and equal thickness. The resulting interface pressure distributions which are presented are sufficiently accurate for the calculation of thermal contact resistance.
