Abstract Double-cantilever beams (DCBs) are widely used to study mode-I fracture behavior and measure toughness under quasi-static loads. Recently, the authors have developed analytical solutions for DCBs dynamic loads with consideration of structural vibration wave propagation. There two methods beam-theory-based data reduction determine energy release rate: (i) using an effective built-in bou...

We present an updated direct measurement of the parity-violating coupling of the Z 0 to strange quarks, A s , derived from the full SLD data sample of approximately 550,000 hadronic decays of Z 0 bosons produced with a polarized electron beam and recorded by the SLD experiment at SLAC between 1993 and 1998. Z 0 → s¯ s events are tagged by the presence in each event hemisphere of a high-momentum...

We present a preliminary direct measurement of the parity violating coupling of the Z 0 to strange quarks, A s , derived from a sample of approximately 300,000 hadronic decays of Z 0 bosons produced with a polarized electron beam and recorded by the SLD experiment at SLAC between 1993 and 1997. Z 0 → s¯ s events are tagged by the presence in each event hemisphere of a high-momentum K ± , K 0 s ...

In the present paper, electrical energy harvesting from random vibrations of an Euler-Bernoulli nano-beam with two piezoelectric layers is investigated. The beam is composed of an aluminum layer together with two piezoelectric ceramic layers (PZT 5A) serving as energy harvesting sensors. In the proposed method, the equations governing the bimorph nano-beam will be analytically derived using cla...
