Semilinear Systems of Weakly Coupled Damped Waves
… solutions to the Cauchy problem for semilinear damped wave equations with an effective dissipation term, where the data are supposed to belong to different classes of regularity. We apply these results to the Cauchy problem for weakly coupled systems of semilinear effectively damped waves with …

Nonlinear optimum design of dynamic damped structures
<p>"A method to optimize the weight of plane frames subjected to dynamic loads is presented. Restrictions are imposed upon the maximum dynamic stresses and displacements, desirable section moduli of the constituent members, and the range of values allowed for natural frequencies. Various …

Perturbation methods for slightly damped gyroscopic systems
This dissertation concerns the development of a perturbation theory applicable to the algebraic eigenvalue problem. The objective is to express the perturbed eigenvalues and eigenvectors in terms of the unperturbed eigenvalues and eigenvectors and the perturbing matrices, without solving a new …

Energy bounds on point-wise damped wave operators
… produced correspond to those modes of the undamped string that have nodes at the contact point; the others are damped by the action of the finger. Bamberger, Rauch, and Taylor [1] modeled the phenomenon with point-wise damping and suggested that the "correct touch" (force applied by the …

Simulation of the dynamic response of a damped taught string
Marine pipeline are facing new issues involved by the increase of the depth of exploited oil and gas reservoirs. This thesis discusses the changes in the dynamic behavior of marine pipelines and proposes a simple simulation based on a taut string. The dynamic response of the taut string is modeled …
