WebThe periodic flexural-gravity waves propagating along a frozen channel are investigated. The channel has a rectangular cross section. The fluid in the channel is inviscid, incompressible and covered with ice. The ice is modeled by a thin elastic plate whose thickness varies linearly. Two cases have been considered: the ice thickness varies symmetrically across … Web19 de set. de 2002 · Abstract.

Web21 de out. de 1999 · First of all, the closed form solution for the natural frequencies and the corresponding normal mode shapes of the uniform beam alone (or the “bare” beam) … Web31 de mar. de 2024 · Flexible beams are usually modeled under the assumption of large displacement, finite rotation, but with small strains. Such hypothesis allows the equation of motion to be built using co-rotational finite elements. The co-rotational formulation decomposes the total motion of a structural element into two parts: a rigid body and an … WebChen, D.W.
