Fourth-order elastic constants of β-brass
Combinations of the fourth-order elastic constants of beta -brass (Cu--44.3Zn, Cu--48.3Zn) were calculated using the measured second-order and third-order elastic constants and the expressions for the effective elastic constants of a cubic crystal obtained from finite-strain theory. The present calc...

| description | Combinations of the fourth-order elastic constants of beta -brass (Cu--44.3Zn, Cu--48.3Zn) were calculated using the measured second-order and third-order elastic constants and the expressions for the effective elastic constants of a cubic crystal obtained from finite-strain theory. The present calculations show that the Cauchy relations for the fourth-order elastic constants in beta -brass are not satisfied. This implies that noncentral or many-body forces occur in this material. The higher-Zn alloy shows lower magnitudes of the fourth-order elastic constants and a larger Cauchy discrepancy. 5 ref.--AA |
