| Title: | On the determination of the elastic constants of tetragonal crystals with application to strontium molybdate | Authors: | Lee, W.Y. Kok, W.C. |
Issue Date: | Mar-1989 | Citation: | Lee, W.Y., Kok, W.C. (1989-03). On the determination of the elastic constants of tetragonal crystals with application to strontium molybdate. Solid State Communications 70 (4) : 459-460. ScholarBank@NUS Repository. | Abstract: | A method is proposed to determine the elastic constants of tetragonal crystals from measured velocities of ultrasonic waves. The optimization procedure is based on minimizing Z = ∑n j=1y2 j where yj is the secular determinant obtained from Christoffel's equations. Such a criterion offers a direct measure of the accuracy of the calculated elastic constants viz-a-viz the experimental wave velocities. The method is applied to strontium molybdate. © 1989. | Source Title: | Solid State Communications | URI: | http://scholarbank.nus.edu.sg/handle/10635/97423 | ISSN: | 00381098 |
