Effects of Rolled Plate Thickness on Anisotropy, with Application to Acoustic Stress Measurement
- 132 Downloads
Common structural materials which are normally idealized as isotropic for most engineering purposes must be considered anisotropic for purposes of acousto-elastic stress measurement. The degree of anisotropy affects the number of moduli, as well as their departure from the usual isotropic values. For instance, rolled plates made of the same alloy, with the same temper designation, may have different moduli for different amounts of rolling. It is the purpose of this paper to determine whether the acousto-elastic constants are identical for commercial rolled plates of the same alloy and temper but different thicknesses.
