Computational Assessments on Transversal Vibration of Large Beams due to Impulsive in-Motion Actions

This study deals with the area of condition monitoring and dynamic damage detection in composites based structural parts embedding insulation systems. The paper contains a briefly presentation of some particular and inad...

NONLINEAR APPROACH OF THE SYSTEMS BETWEEN THE DYNAMIC MODELLING DIFFICULTIES AND THE ADVANTAGES OF USING IT IN MECHANICAL DESIGNING

On the Stability of a Class of Non-Ideal Systems

A vibrating system is said ideal when its excitation is not influenced by the response of the system. When the excitation is influenced by the response of the system, the system is said non-ideal. A new degree of freedom...

The Linear Viscoelastic Behavior of the Asphalt Mixture to the Haversine Impulsive Dynamic Actions Specific in Road Traffic

In this work is analyzed the behavior of the asphalt mixture under the action of dynamic traffic, and the contact between wheel and track is modeled as a dynamic excitation function of haversine type.

Assessment of Damages in Sandwich Panels Based on the Damage Location Indexes

This paper presents a methodology to locate and evaluate transversal damages in composite structures, based on natural frequency shifts due to damage. In previous researches the authors succeeded to contrive a relation b...
