TL;DR: In this paper, a feasibility study is performed for a bifunctional thermoelectric generator applied in vehicle engines, which can use Seebeck effect for waste heat recovery and Peltier effect for engine warm-up.

TL;DR: In this paper, a finite element analysis has been performed to understand the fracture process of ultrasonically cutting through a brittle material and the stress state at the crack tip was analyzed by numerical determination of the stress intensity factor for a three-dimensional crack loaded on its faces by displacements corresponding to the modal amplitudes of the excited blade.

TL;DR: In this article, the authors present an approach to block horn design, which relies on two laser-based vibration measurement techniques, electronic speckle pattern interferometry (ESPI) and laser doppler velocimetry (LDV) modal analysis, to validate finite element (FE) models.

TL;DR: In this paper, the authors investigated the contributing influences of the ultrasonic generator signal to the vibration response of the cutting system components, which led to enhanced control of vibration transmission to the cutting edge at the tuned frequency.
