This paper presents a detailed experimental validation of an orthotropic laminate model to predict the vibroacoustic behavior of flat sandwich-composite plates with foam core. The accuracy of the model is investigated using a thin sandwich plate over a large frequency band. The sound transmission loss (STL) across several clamped sandwich-composite plates with polyurethane foam core is compared for different core density, different core thickness and different skin thickness.

The objective of this study is to develop a model to describe accurately the vibroacoustic performance of a clamped finite orthotropic laminated double-composite plate filled with air. In this investigation, the theoretical and existing experimental results were compared and reached a good agreement. The influence of several key system parameters (e.g., thickness of faceplate, the thickness of air cavity and the sound incident angles) on sound transmission loss is considered.

This paper proposes an optimization procedure for maximization of the biaxial buckling load of laminated composite plates using the gradient-based interior-point optimization algorithm. The fiber orientation angle and the thickness of each lamina are considered as continuous design variables of the problem.

A high-order displacement field in quadrilateral element with nine nodes and twelve-degrees-of-freedom per node is developed for bending analysis of thick arbitrary layered composite plates under transverse loads. Results for plate deformations, internal stress-resultants and stresses for selected examples are shown to compare well with the closed-form and other finite element solutions.

This research presents a new model for vibration analysis of thick laminated plates on a non-homogeneous elastic foundation by the Dynamic Stiffness Method (DSM). The non-homogeneous foundation consists of multi-segment Winkler-type and Pasternak-type elastic foundation. The Dynamic Stiffness Matrices using the First Shear Deformation Theory (FSDT) are constructed for cross-ply thick composite plates.
