A photoelastic investigation of thermal stresses.

This report describes a photoelastic technique for the evaluation of thermal stresses in models fabricated of paraplex p-43. The optical and physical properties of this polyester resin were determined over the temperature range from room temperature to -40°F. Details of the techniques of casting...
