Approximate critical curves in exponentially damped nonviscous systems

Lázaro, Mario (Elsevier, 2019-05-01)

[EN] In this paper a new approximate numerical method to obtain critical curves in exponentially damped nonviscous systems is proposed. The assumed viscoelastic forces depend on the past history of the velocity response ...
Closed-form eigensolutions of nonviscously, nonproportionally damped systems based on continuous damping sensitivity

Lázaro, Mario (Elsevier, 2018)

[EN] In this paper, nonviscous, nonproportional, vibrating structures are considered. Nonviscously damped systems are characterized by dissipative mechanisms which depend on the history of the response velocities via ...
Critical damping in nonviscously damped linear systems

Lázaro, Mario (Elsevier, 2019-01)

[EN] In structural dynamics, energy dissipative mechanisms with nonviscous damping are characterized by their dependence on the time-history of the response velocity, mathematically represented by convolution integrals ...
Eigensolutions of nonviscously damped systems based on the fixed-point iteration

Lázaro, Mario (Elsevier, 2018)

[EN] In this paper, nonviscous, nonproportional, symmetric vibrating structures are considered. Nonviscously damped systems present dissipative forces depending on the time history of the response via kernel hereditary ...
Exact determination of critical damping in multiple exponential kernel-based viscoelastic single-degree-of-freedom systems

Lázaro, Mario (SAGE Publications, 2019-12)

[EN] In this paper, exact closed forms of critical damping manifolds for multiple-kernel-based nonviscous single-degree-of-freedom oscillators are derived. The dissipative forces are assumed to depend on the past history ...
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 ...
