Uncertainties in structural dynamics for composite sandwich panels

This paper concerns uncertainties in structural dynamics for composite sandwich panels constituted of two thin carbon-resin skins and one high stiffness closed-cell foam core. Each skin is constituted of two unidirectional plies [60/-60]. Such light composite sandwich panels, manufactured with a same process, generally present a significant dispersion for their Frequency Response Functions (FRF...

Optimization of Composite Sandwich Cover Panels Subjected to Compressive Loadings

An analysis and design method is presented for the design of composite sandwich cover panels that includes transverse shear e ects and damage tolerance considerations. This method is incorporated into a sandwich optimization computer program entitled SANDOP. As a demonstration of its capabilities, SANDOP is used in the present study to design optimized composite sandwich cover panels for transp...

Free vibration analysisof soft-core composite-faced sandwich plates using three-dimensional finite element method

In this paper, natural frequencies of the sandwich plates with soft flexible core and composite face sheets are obtained. Three-Dimensional (3D) finite element method (FEM) is used for constructing and analyzing of the sandwich plates to obtain their natural frequencies. Continuity conditions for transverse shear stresses at the interfaces as well as transverse flexibility and transverse normal...
