This paper is aimed to examine the dynamics of cracked thin rectangular plates subjected a moving non-stationary random load. A load considered with constant mean value, velocity along plate, and five different covariance patterns,the white noise, constant, exponential, cosine wave, exponential covariance. Accordingly, an intact plate’s orthogonal polynomials in combination well-known corner fu...

Vortex structures made by impulsively translating low aspect-ratio plates are studied experimentally using defocusing digital particle image velocimetry. The investigation of translating plates with a 90◦ angle of attack is important since it is a fundamental model for a better understanding of drag-based propulsion systems. Rectangular flatrigid, flexible and curved-rigid thin plates with the ...

The paper describes three different rectangular plate bending elements based on Reissner's type stationary variational principles. They differ in the number of dependent variables approximated independently and also in the number of nodes per element. The first element types treats the transverse deflection and the three moments as unknowns at each of the corner nodes; the second element type t...

Surface smoothing applied to range/elevation data acquired using a variety of sources has been a very active area of research in computational vision over the past decade. Generalized splines have emerged as the single most popular approximation tool to this end. In this paper we present a new and fast algorithm for solving the surface smoothing problem using a membrane, a thin-plate, or a thin...
