Machining is among the most versatile material removal processes in the manufacturing
industry. To better optimize the machining process, the knowledge of shear strains and …

Increased arterial stiffness is associated with atherosclerosis in humans, but there have
been limited animal studies investigating the relationship between these factors. We bred …

Modern turbomachinery blades have extremely low inherent damping, which can lead to
high transient vibrations and failure through high-cycle fatigue. Smart materials enable …

This paper extends the resonance frequency detuning (RFD) vibration reduction approach
to cases of turbomachinery blade mistuning. Using a lumped parameter mistuned blade …

Piezoelectric-based semi-active vibration reduction techniques typically rely on rapid
changes in the electrical boundary conditions or corresponding stiffness state. Approaches …

This letter reports on the induced mechanical transients for piezoelectric-based, state-
switching approaches utilizing both experimental tests and a numerical model that more …

Modern turbomachinery blades have extremely low inherent damping, which can lead to
high transient vibrations and failure through high-cycle fatigue. Recent research seeks …

Turbomachinery blade technology has recently trended towards the use of monolithic
bladed disks. Although offering a wealth of benefits, this construction removes the blade …

T blades experience periodic forcing from rotor-stator airflow interaction and rotation effects.
This periodic forcing causes blade vibration which, over time, can lead to high-cycle fatigue …

Unexpected vibration of aero-engine blades may lead to fatigue failure. In order to reduce
the harmful vibration of aero-engine blades, many smart materials have been employed for …
