Abstract
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 and fabricating the models are
given. Tuokerman optical strain gages were utiliized in the
determination of the modulus of elasticity and the thermal expansion
coefficient. Experimental investigations were conducted into the problems
of an annulus contracting upon a steel plug, and the thermal stresses
established by steady state heat transfer in a oircular cylinder. The
data obtained were correlated with theory utilizing the properties
of the photoelastio material obtained in the calibration*
