Elastic Properties

Abstract

The second-order elastic stiffness [C] and compliance tensors [S] are defined by the generalized Hooke's law: ½X ¼ ½C½e or ½e ¼ ½S½X, where [X] and [e] are, respectively, the elastic stress and strain tensors which have six components. The elastic tensors [C] and [S] are second-order fourth-rank and have symmetric 6 Â 6 components. Their explicit tensor forms are given in Adachi [1]. We present in Tables 3.1-3.3 the elastic stiffness and compliance constants for a number of group-IV, III-V and II-VI semiconductors used for obtaining alloy values.
