The use of an automatic recording microdensitometer in conjunction with a fringe multiplying polariscope for analysing small portions of slices from frozen stress photoelastic models is described in detail. The method is used to find the load distribution in the threads of a 30 mm ISO nut and bolt model. The accuracy is discussed and shown to be comparable to that of conventional photoelastic techniques.
