Book Description
In this article, the natural frequencies, damping ratios, and damping constants of plates in different materials such as Steel, Aluminum, and Copper, with different boundary conditions like clamped-clamped-clamped-clamped (CCCC), clamped-clamped-clamped-free (CCCF), clamped-clamped-free-free (CCFF), clamped-free-free-free (CFFF) and free-free-free-free (FFFF), have been experimentally investigated. Natural frequencies obtained experimentally are compared to the natural frequencies obtained from numerical analysis using finite element analysis package ANSYS. The effects of different parameters like density, boundary conditions, and fixed edge length on free vibration characteristics of the plates are discussed. The damping ratios are determined experimentally, and the effect of boundary conditions on the damping ratio is also discussed.

Book Description
Vibration of Functionally Graded Beams and Plates uses numerically efficient computational techniques to analyze vibration problems associated with FG beams and plates. Introductory material on FG materials and structural members, as well as a range of vibration and shear deformation theories are discussed, providing a valuable summary of these broader themes. The latest research and analysis of vibration in FG materials is presented in an application-oriented manner, linking the research to its importance in fields such as aerospace, nuclear power, and automotive engineering. The book also features research on the complicating effects of thermal environments, piezoelectricity, and elastic foundations. The innovative computational procedures and simulation results are shown in full throughout, providing a uniquely valuable resource for users of numerical modeling software. This book is essential reading for any researcher or practitioner interested in FG materials, or the design of technology for the nuclear power, aerospace, and automotive industries. Defines the basic preliminaries of vibration and FG materials Introduces historical background and recent developments in functionally graded materials with references for further reading Shows computational procedures with simulation results Includes many easy to understand example problems Presents various analytical and numerical procedures for each solution

Book Description
A systematic approach to the free vibration analysis of thin, flat, non-rectangular quadrilateral plates with combinations of simple and clamped supports is presented, using the parallelogram plate as an example. Modifications that Saliba made for the right-triangular plate to the building block superposition method developed by Gorman are implemented. The superposition method is an analytical solution. No simplifications are made to take advantage of the point symmetry of the parallelogram plate, keeping the solution general. The whole plate is divided into two right-triangular and one rectangular segment. Rectangular building blocks are superimposed for each of the segments to meet the required net boundary conditions and the conditions of continuity along the segment interfaces. The Levy-type solution to the eight building blocks used are given, along with the necessary Fourier expansions and a comprehensive guide to assembling the eigenvalue matrix. Numerical results for a wide variety of plates are presented, including numerous mesh and contour plots. Comparison is made to previously published data. The results for the fully clamped parallelogram plate are supported by experimental results. Six aluminum plates were tested for the first six resonance frequencies and the first three mode shapes. Details of the simple, yet highly accurate experimental method are included.
