ABSTRACT
The equations of equilibrium for a symmetric composite laminate were presented in Sections 10.2. Boundary conditions consistent with thin-plate theory were then discussed in Section 10.3. Unfortunately, exact solutions to the equations of equilibrium that satisfy specified boundary conditions often cannot be found. Sometimes the difficulty in obtaining an exact solution is due to the boundary conditions involved; difficulties of this sort are encountered for both isotropic and anisotropic plates. In other cases, the difficulties are strictly due to the anisotropic nature of composites.
