Preface: Developments in understanding the dynamical behavior of mechanical, civil, aerospace and naval structures and their applications

Abstract

Many engineers and most of the general public have been formed under the vision that structures are static systems built to preserve the form and avoid ruin of an engineering object such as a car, a bridge, an airplane, an offshore oil rig etc. This vision leads to neglect one of the more obvious human sensations: the fact that the time passes and nothing stays quite the same. The main objective of the dynamics of structures is to deal with the passage of time and its consequences upon structures, specially accounting for the kinetic energy and inertial forces that arise from non-negligible velocities and accelerations.

The selected contributions of this special issue falls on a series of interesting problems related to recent developments in nonlinear dynamics and control of structures been designed for state of art
mechanical, civil, aerospace and naval applications. This special issue contains 14 papers selected by revisions.
