Abstract The mean wake of a three-dimensional surface-mounted rectangular flat plate was studied experimentally in low-speed wind tunnel for four different aspect (height-to-width) ratios, AR = 3, 2, 1, and 0.5. Reynolds number based on the width Re 3.8 × 10 4 boundary layer thickness ground plane, relative to width, δ / W 1.1. incidence angle varied from α 0° (where is normal flow) 90° paralle...

Many composite cantilever plate-like structures have found engineering applications in different industries. For attaining a meaningful assessment of the plate vibration characteristics, it is important to efficient and effective methods for determining natural frequencies/mode shapes plates. In this paper, method formulated on basis Ritz simple first-order shear deformation theory (SFSDT) pres...

This study concerns the dynamic characteristics of a prestressed isotropic, rectangular plate continuously supported by an elastic foundation and carrying accelerating mass M. Closed form solutions of the governing fourth order partial differential equations with variable and singular coefficients are presented. For the twodimensional plate problem, the solution techniques is based on the doubl...

An analytical model for creating flat Chladni figures is presented. The equation of a standing wave in the simplest boundary conditions and Fourier transform are used. Top view images shown at different frequencies. practical significance results obtained further development field based on waves physical nature has been determined.

In this paper, deformations of a laminated composite plate due to mechanical loads are presented. Third order shear deformation theory of plates, which is categorized in equivalent single layer theories, is used to derive linear dynamic equations of a rectangular multi-layered composite plate. Moreover, derivation of equations for FEM and numerical solutions for displacements and stress distrib...

Finite difference method is used to calculate the via-plate capacitances for vias with pad. Due to the symmetric structure, the solving domain is reduced to a rectangular ρ − z region. Boundary conditions along the region are discussed. Both barrel-plate and pad-plate capacitances are studied with various geometric parameters. The results could be used as validations for possible analytical exp...

We consider here the Cauchy problem for the full system of dynamic Von KK armm an equations, which is a model for the vibrations of a nonlinear elastic plate. We prove global existence and uniqueness of nite energy solutions in the case of an innnite plate. We show then that our methods and results still hold for a rectangular plate which is simply supported or clamped at the boundary. Moreover...
