TL;DR: In this article, the finite element displacement method was used for the analysis of free vibration of plates and shells, and for the simulation of forced response and forced response analysis of rigid and flexible plates.

TL;DR: In this article, the propagation of vibration generated by a harmonic or a constant load moving along a layered beam resting on the layered half-space is investigated theoretically in a railway track, where the ground is modelled as a number of parallel viscoelastic layers overlying an elastic half space or a rigid foundation.

TL;DR: In this article, a model for the propagation of vibration in the ground from a stationary oscillating load applied via a railway track structure is presented, which includes the track as an infinite layered beam structure resting on a ground made up of infinite parallel homogeneous elastic layers.

TL;DR: In this article, a twenty node, isoparametric acoustic finite element model is developed for analysing the acoustic modes of irregular shaped cavities, which is first used to analyse a rectangular enclosure.

TL;DR: In this article, a method is presented for using the finite element technique to evaluate the phase constant of an arbitrary periodic structure, which is applied to two types of periodic construction, a periodically supported infinite beam and a skin rib structure.
