INFLUENCE OF TRANSVERSE SHEAR AND EDGE CONDITION ON NONLINEAR VIBRATION AND DYNAMIC BUCKLING OF HOMOGENEOUS AND SANDWICH PLATES,
Abstract
In a previous paper the variational equation of motion was applied to the nonlinear analysis of dynamic buckling of simply supported homogeneous (Timoshenko beam) and sandwich plates executing plane-strain motion. To investigate the influence of the edge condition and the interaction between the edge condition and transverse shear effect, the analysis is further extended in this paper to such plates with clamped edges. Results show that the transverse shear effect is much greater for sandwich than for homogeneous plates. They further show that the shear effect is always greater for the clamped than for the simply supported case and is in fact not entirely negligible even for a homogeneous plate if it is clamped. The same conclusions apply to nonlinear vibrations of such plates, which are also investigated. (Author)
