Composite plates with 0^o plies

The modal parameters are compared for first four modes namely:

• first bending mode in longitudinal direction (B1),
• second bending in the longitudinal direction (B2),
• second bending mode in both longitudinal and transverse direction (B22) and
• first torsion mode (T1).

Typical first four mode shapes are shown in Figure 38.1.
