Postbuckling behavior of rectangular plates
Unlike simple columns, rectangular plates which are supported on all edges may carry considerable load beyond their buckling load. Under some conditions it may be advantageous to utilize this additional load-carrying capacity. Von Karman has presented the basic nonlinear differential equations for …

Wave impacts on rectangular structures
There is a good deal of uncertainty and sensitivity in the results for wave impact. In a practical situation, many parameters such as the wave climate will not be known with any accuracy especially the frequency and severity of wave breaking. Even if the wave spectrum is known, this is usually …

Algorithms for Rectangular Robot Motion Planning
… the input objects (robots and/or obstacles) are rectangular objects with bounded aspect ratio; that is, the side lengths of the objects are similar in proportion to each other.</p><p>Motivated by applications to motion planning and others,we explore the problem of computing and decomposing the …

Supersonic Corner Flows in Rectangular Channels
Rectangular channel geometries are widely encountered in supersonic flows, such as in wind tunnels and in aircraft inlets. Shock-boundary-layer interactions in these flows are known to exhibit significant three-dimensionality, due to the presence of sidewalls and associated corner boundary layers. …

The vibrational spectra of rectangular plates
… to excite and measure modes of vibration of thin rectangular plates. The frequency spectra of different modes have been investigated as a function of the material elastic moduli and the plate geometry. Most of the work was carried out on isotropic materials. For square plates a wide selection of …

Turbulent flow through a rectangular channel
… at 80 normal locations across a two-inch high rectangular water channel. A two polarization, three beam He-Ne Laser-Doppler Velocimetry system was used. The water channel was specifically designed and constructed to facilitate these optical measurements. It had negligible vibration and flow …
