Improving the energy conversion efficiency of piezoelectric energy harvesters is of great importance, and one approach is to make more uniform use of the working material by ensuring a uniform strain state. To achieve better performance, this paper p

Knowing the nature of damping in piezoelectric energy harvesters can lead to proper damping and electromechanical models and designing highly efficient harvesters with less damping. As an attempt toward a better understanding of damping in piezoelect

Experimental investigation of debris entrapment in annular contacts

Autor: Z Clark, J Aleksejev, DA Hills, John E. Huber

In wearing contacts, a part of the wear debris is trapped between the surfaces, creating a wear debris bed. Many researchers report such beds providing a degree of protection against further wear. It was hypothesized, that in an annular contact, the

Wire materials for scanners in the large hadron collider: an unusual materials selection problem

Autor: Raymond Veness, Alan C.F. Cocks, Hal Bigland, John E. Huber

The transverse distribution of particles in the hadron beam of the Large Hadron Collider (LHC) is measured using wire scanners that pass a thin wire through the hadron beam and detect scattered radiation. Increasing demands on beam instrumentation in

Periodic domain patterns in tetragonal ferroelectrics are explored using a phase field model calibrated for barium titanate. In this context, we discuss the standard periodic boundary condition and introduce the concept of reverse periodic boundary c
