The deformed shape of the panel is shown in Fig. 7.49. Note that displacements u
and u correspond to the panel reference plane which is the contact plane of 0 and 90
layers (see Fig. 5.13).
Another typical antisymmetric structure is the two-layered angle-ply laminate
shown in Fig. 5.14. Using stiffnesscoefficientsof this laminate found in Section 5.7
and Eqs. (7.25) and (7.27), we can write Eqs. (7.23) in the following form:
