TL;DR: In this article, the authors compared numerical results and some analytical prediction formulae available for fatigue damage evaluation; amongst all expressions, a new proposed original approach was shown to give sound theoretical framework and improved results.

TL;DR: In this article, the shape of scavengers is optimized to increase the specific power generated per unit of scavenger volume by optimizing shape of the scavengers, and two optimized trapezoidal configurations are identified and analyzed.

TL;DR: In this paper, fatigue analysis of broad-band Gaussian random processes is discussed, with attention focused on the distribution of rainflow cycles and the fatigue damage under the linear rule, and several spectral methods are reviewed: the narrowband approximation, the Wirsching-Light formula, Dirlik's amplitude density, the Zhao-Baker technique, together with an approach recently developed by the authors, as well as a new (completely empirical) method.

TL;DR: In this article, a preliminary investigation on energy harvesting from human walking via piezoelectric vibrating cantilevers is presented, where the transient electromechanical response and the harvested power of a shoe-mounted bimorph cantilever excited by the standard acceleration signal are computed by numerical simulations and compared with measurements on a real prototype.

TL;DR: In this paper, a frequency-domain formulation of a stress invariant based multiaxial fatigue criterion, called "Projection by Projection" (PbP) approach, was proposed for estimating fatigue life in presence of complex multi-xial loadings.
