In tire industry, it is very crucial to evaluate physical and mechanical properties of the rubber which is used for production of the tire, to ensure the quality of the final product. Resilience is an important property of a rubber, which cannot be evaluated through direct measurement in production cycle in this industry. Therefore, non-destructive ultrasonic testing, which has been used in man...

The present work focuses on geometrically exact finite elements for highly slender beams. It aims at the proposal of novel formulations of Kirchhoff-Love type, a detailed review of existing formulations of Kirchhoff-Love and SimoReissner type as well as a careful evaluation and comparison of the proposed and existing formulations. Two different rotation interpolation schemes with strong or weak...

development of ultrasound technique has not been progressing for evaluating the internal quality of fruits as fast as that of processed foods. in this research for quality assessment of pear fruit (shah miveh variety) an ultrasonic measurement system was constructed to transmit and receive the ultrasonic waves. the apparatus included a pulser-receiver, a pair of 75 khz ultrasonic transducers wi...

In this paper, we consider transverse steady oscillations of a piezoactive bimorph in the formulation plane deformation. The problem is solved within framework linear thermoelectroelasticity, while temperature separately and distribution taken into account constitutive relations electroelasticity. On basis Kirchhoff-Love type hypothesis for mechanical quantities symmetric quadratic electric pot...

In this paper we present a cost effective method to fabricate flexible, high density piezoelectric tape, and expl'ore its potential application as a new type of Lamb wave phased array for Structural Health Monitoring (SHM) through simulating the Lamb wave propagation generated from single element and multielement arrays. The piezoelectric tape consists of many patterned and densely packed PZT (...

We report an x-ray diffraction study on the charge-density-wave (CDW) LaTe3 and CeTe3 compounds as a function of pressure. We extract the lattice constants and the CDW modulation wave-vector, and provide direct evidence for a pressure-induced quenching of the CDW phase. We observe subtle differences between the chemical and mechanical compression of the lattice. We account for these with a scen...

Surface acoustic wave (SAW) sensors have been applied in various areas with many advantages, such as their small size, high sensitivity and wireless passive form. Love mode sensors, an important kind of SAW sensor, are mostly used biology chemistry monitoring, they can be a liquid environment. Common consist delay line waveguide sensitive layers. To extend the application this article reports n...

Shockwave is a rapid, short duration acoustic wave that carries energy and can propagate through tissue medium. This kind of physical force can be a mechanical stimulus that induces biological effects in living tissue. Extracorporeal shockwave therapy (ESWT) acts as a mechanical stimulus which promotes biological healing processes through a mechanotransduction. The biological effects of ESWT ar...
