Abstract:
Experimentation was done on static test methods for obtaining elevated temperature measurements of Poissons ratio and shear modulus of sheet material. A method for measuring Poissons ratio employing mechanical transmission of transverse strain from the test section of the specimen to an optical extensometer appeared feasible. This method will need modification for utility at elevated temperature. Efforts to measure shear modulus in flat sheet specimens were not successful. It was apparently not possible to obtain a shear deflection with definite boundaries in a flat sheet. The use of cylindrical specimens would avoid this difficulty. These were tried, but a torque load free of bending could not be applied in existing facilities. Author
