306 The Elastic Solid

and

We note also that the stiffness matrix for transverse isotropy has also been written in the
following form:

where we note that there are five constants A, ^7-, jM^, a and ft.

5.27 Constitutive Equation for Isotropic Unearty Elastic Solids

The stress strain equations given in the last section is for a transversely isotropic elastic solid
whose axis of transverse isotropy is in the 63 direction. If, in addition, e^ is also an axis of
transverse isotropy, then clearly we have

and the stress strain law is
