In order to further predict theoretically the mechanical properties such as hardness ([H.sub.V]) and crack, the bulk modulus (B), shear modulus (G), hardness ([H.sub.V]), and universal elastic anisotropy index ([A.sup.U]) values are shown in Table 7.
where [epsilon] is the volume strain, [T.sub.0] is the initial temperature, T - [T.sub.0] is the change in temperature, [[beta].sub.b] is the volume thermal expansion coefficient of solid skeleton, [P.sub.e] is the effective pressure, and [K.sub.d] is the bulk modulus of drainage.
The bulk modulus appears to be less sensitive than the shear modulus to the relaxation that occurs after the application of the homogeneous strain.
