On Aspects of Asymptotics for Axially Moving Continua

In this thesis two models for axially moving continua have been studied: a string-like model and a beam-like model. Mathematically, a string-like model is described by a wave equation and a beam-like model is usually described by the Euler-Bernoulli beam equation. A string-like model has been used to describe the transversal vibrations of a...

On aspects of boundary damping for cables and vertical beams

Elastic structures are susceptible to wind- and earthquake-induced vibrations. These vibrations can damage a structure or cause human discomfort. To suppress structural vibrations, various types of damping mechanisms, active or passive, can be applied. In this thesis the model of a weakly damped, standing Euler-Bernoulli beam in a (turbulent)...
