ABSTRACT
A linear elastic anisotropic medium was dened in Chapter 9. At that stage, we reported, without justication, the elastic behavior relationships characterizing the particular case of orthotropic materials, then isotropic transverse. We propose now to examine more closely the elastic constants that appear in stress-strain relationship for these materials. In the case of transversely isotropic materials, we will study also the manner in which the constants change with the coordinate system.
