Computation of eigenvalues in proportionally damped viscoelastic structures based on the fixed-point iteration

Lázaro Navarro, Mario; Pérez Aparicio, José Luis; Epstein, M. (Elsevier, 2012-12-15)

Linear viscoelastic structures are characterized by dissipative forces that depend on the history of the velocity response via hereditary damping functions. The free motion equation leads to a nonlinear eigenvalue problem ...
Multiparametric computation of eigenvalues for linear viscoelastic structures

Lázaro, Mario; Pérez-Aparicio, José L. (Elsevier, 2013-02)

A new methodology for the computation of complex eigenvalues for multi-degree-of-freedom linear viscoelastic structures is presented. It is assumed that damping matrix does not only depends on the frequency but also on a ...
The Eigenvalue Problem in Linear Viscoelastic Structures: New Numerical Approaches and the Equivalent Viscous Model

Lázaro Navarro, Mario (Universitat Politècnica de València, 2013-06-25)

El análisis y el control de las vibraciones cobra especial importancia en muchas ramas de la ingeniería, en especial la ingeniería mecánica, civil, aeronáutica y automovilística. Tal es así que prácticamente se identi¿ca ...
