Free vibration characteristics of longitudinally sti!ened square panels with symmetrical square cutouts are investigated by using the "nite-element method. A rectangular shell element with seven degrees of freedom per node together with a beam element of seven degrees of freedom per node is used for
The "deficient" system that exists when the geometric multiplicity of an eigenvalue of a linear vibrating system is less than its algebraic multiplicity is defined and constructed. A complex mode theory is developed for the deficient system. The normal complex modes and generalized complex modes are
