Measurement of Thermal Stresses at -320°F by Strain Gages
In connection with the theoretical evaluation of an aluminum tank for liquid nitrogen storage, it was necessary to experimentally confirm the expected low thermal stress level. For an adequate investigation of these stresses 50 gaging locations were required. To our knowledge strain gages had never been used on such a scale at this low temperature level, and of even greater concern was the complete lack of experience with strain gages to measure thermal stresses at low temperatures.
