Eliminating the body-force effect in stress-frozen models

An extremely small forces are employed for loading stress-frozen photoelastic models, the weight of the model often contributes a disproportionately large share of the total model loading. This technical note examines the problem for a typical model analysis and several practical methods of eliminating the body-force effect are presented
