As. Gendy et al., FREE-VIBRATIONS AND STABILITY ANALYSIS OF LAMINATED COMPOSITE PLATES AND SHELLS WITH HYBRID MIXED FORMULATION/, Computers & structures, 63(6), 1997, pp. 1149-1163
Modern theory for applications of laminated plates and shells calls fo
r detailed study of the effect of large spatial rotations on the geome
tric stiffness for stability analysis as well as inertia operators for
vibrations. These two issues are carefully examined here in conjuncti
on with the recently developed mixed finite element formulation for pl
ates and shells with low-order displacement/strain interpolations. An
extensive set of stability and vibration problems has been solved to d
emonstrate the effectiveness and general utilities of the formulation
described for laminated plate and shells with arbitrary geometry. (C)
