Progress in the design and structural analysis of commercial jet engine fan blades is
reviewed and presented. This article is motivated by the key role fan blades play in the …

Resonant vibration condition involves a drop in the life-cycle of the components and is one
of the main causes of high cycle fatigue failure (HCF) in turbomachinery blades. As a …

Active and passive vibration control systems are of paramount importance in many
engineering applications. If an external load excites a structure's resonance and the …

An experimental facility for testing full-scale bladed disks in vacuum conditions and under
centrifugal load is described in this paper. The special feature of the PHARE# 1 test rig is its …

Vibration mitigation is a prominent matter in several engineering fields. Several adverse
phenomena are related to vibrations, such as fatigue, noise, etc. The availability of smart …

Gas turbine blade vibrations can give rise to catastrophic failures, and cause a reduction of
the blades' life due to fatigue-related phenomena. Damping is often required to improve …

Severe resonant vibration is one of the main roots of turbomachinery blades failure. Forced
response issues arise when the blades work in non-uniform flow fields. As a result unsteady …

Vibration suppression systems are often crucial to extend the life cycle of the structures in
several engineering fields. The passive systems are the most commonly used but, in case of …

Analytical and experimental investigations of active damping of free vibrations of a cantilever
viscoelastic beam assembled together with the piezoelectric actuator and piezoelectric …

In recent decades, many studies have been conducted on the use of smart materials in order
to dampen and control vibrations. Lead zirconate titanate piezoceramics (PZT) are very …
