ABSTRACT
The linear elastic anisotropic medium was defined in Chapter 9. At that stage, we reported, without justification, the elastic behavior relationships characterizing the particular case of orthotropic materials, then isotropic transverse. We propose, in this chapter, to examine more closely the elastic constants that appear in stress–strain relationship for these materials after rotation about an orthotropic transverse axis. In the case of transversely isotropic materials then in the case of a ply, we will study also the manner in which technical forms of the constants change with the coordinate system.
