Abstract
Using an iterative technique to obtain the exact solutions of the cubic Christoffel equation, the 21 elastic constants of copper sulphate pentahydrate have been determined at 25°C by the ultrasonic pulse echo method. The elastic constants, referred to the IRE recommended system of axes, are c11=5· 65, c12=2· 65, c13=3· 21, c14=-0· 33, c15=-0· 08, c16=-0· 39, c22=4· 33, c23=3· 47, c24=-0· 07, c25=-0· 21, c26=0· 02, c33=5· 69, c34=-0· 44, c35=-0· 21, c36=-0· 16, c44=1· 73, c45=0· 09, c46=0· 03, c55=1· 22, c56=-0· 26 and c66=1· 00 in units of 1010 N m-2.
