As for an isotropic layer considered in Section 4.1, the terms including transverse
normal stress c3can be neglected in Eqs. (4.53) and (4.54) and they can be written in
the following simplified forms:
(4.55)
and
(4.56)
where
Constitutive equations presented above include elastic constants of a layer that are
determined experimentally. For in-plane characteristics El, E?, GI?, and ~12,the
corresponding test methods were discussed in Chapter 3. Transverse modulus E3 is
