DESCRIPTION OF A CALCULATION METHOD OF ELASTIC CONSTANTS OF CRYSTALS

摘要

With the help of the decline method,a computer-aided analysis program of Christoffel equation is des-cribed which makes it possible to calculate elastic and viscous constants of crystals precisely and easily.Theelastic constants of LiNbO3 and Bi12GeO20crystals are calculated with an Apple-Ⅱcomputer and theFortran program suggested,and the calculated data are compared with the values achieved by others.
