摘要:
Novel experiments are described which, using unsophisticated apparatus, permit adequate measurement of the elastic constants of material available in the form of a thin flexible strip. The accuracy attainable is limited, as in standard methods, by the measurement of the thickness of the material. This quantity appears in the calculations raised to the third power in the measurement of both Young’s modulus and the shear modulus.
