Third-order elastic constants of bcc Cu-Al-Ni.
We have measured the changes in the ultrasonic wave velocity, induced by the application of uniaxial stresses in a Cu-Al-Ni single crystal. From these measurements, the complete set of third-order elastic constants has been obtained. The comparison of results for Cu-Al-Ni with available data for other Cu-based alloys has shown that all these alloys exhibit similar anharmonic behavior. By using ...
متن کاملSecond Order Elastic Constants, Third Order Elastic Constants, Pressure Derivatives of Second Order Elastic Constants and the Low Temperature Thermal Expansion of D-tin
The complex behaviour of metals under severe thermal and stress environments is influenced markedly by their elastic properties. Indeed the response of a material tc~ an applied stress is always determined by the elastic constants and their pressure derivatives. Furthermore, both the mechanical and thermodynamic equation;$ of state of a metal that contains dislocations require detailed knowledg...
متن کاملNew Estimates of the Third-order Elastic Constants for Isotropic Aggregates of Cubic Crystals
An improved method, based on an extension of the self-consistent method from the linear theory, is proposed to evaluate the effective third-order elastic constants for isotropic aggregates of cubic crystals. The calculated constants are compared with the Voigt and Reuss-type estimates, which are currently the only other analytical estimates available for these constants. The agreement between c...
متن کاملMeasurement of third-order elastic constants and stress dependent coefficients for steels
Background: There has been little discussion of the third-order elastic constants of steels in the literature until now. In this study, the precise secondand third-order elastic constants of polycrystalline steels were measured under adiabatic and isothermal conditions. Method: Tomeasure theminute change in the propagation time of the elastic wave corresponding to the tensile stress, the unifor...
متن کاملThird- and fourth-order constants of incompressible soft solids and the acousto-elastic effect.
Acousto-elasticity is concerned with the propagation of small-amplitude waves in deformed solids. Results previously established for the incremental elastodynamics of exact non-linear elasticity are useful for the determination of third- and fourth-order elastic constants, especially in the case of incompressible isotropic soft solids, where the expressions are particularly simple. Specifically...
