A sensor based on a Conductive Polymer Composite (CPC), fully compatible with a textile substrate and its general properties, has been developed in our laboratory, and its electromechanical characterization is presented herein. In particular the effects of strain rate (from 10 to 1,000 mm/min) and of repeated elongation cycles on the sensor behaviour are investigated. The results show that stra...

Moiré interferometry is utilized to investigate the time–temperature-dependent deformation of a woven composite substrate used in multilayer circuit board applications. Creep tests are performed at temperatures ranging from 27 to 70◦C, and the resulting longitudinal and transverse displacement fields are measured via moiré interferometry. Measured displacement fields reveal the influence of fab...

[1] PS converted waves observed near Ancona on the Adriatic coast of central Italy, as revealed by teleseismic receiver functions (RFs), vary with earthquake backazimuth and epicentral distance in a manner consistent with a 1-D anisotropic seismic structure. Using reflectivity calculations, we develop a profile of anisotropic seismic velocity through the Adriatic lithosphere at this locality. W...

As one of the convenient and noninvasive sensing approaches, the automatic limb girth measurement has been applied to detect intention behind human motion from muscle deformation. The sensing validity has been elaborated by preliminary researches but still need more fundamental studies, especially on kinetic contraction modes. Based on the novel fabric strain sensors, a soft and smart limb girt...

With huge varieties of fabrics, the first challenge for any performance evaluation is to categorize the vast types of the products into fewer, more homogeneous and thus akin groups. Classification or sorting is arguably the first step of any scientific investigation, and comparison of product quality is meaningful only when conducted within a group of comparable products. A new criterion termed...

The Chadegan metamorphic complex is a WNW-ESE- trending antiformal structure located in Sanandaj-Sirjan structural zone, Iran.The inner core of the structure is made of orthogneiss, containing eclogitic lenses. Schists and marbles lie structurally above theorthogneiss and crop out in the external limbs of the antiformal dome. Two main deformational episodes have been documented in theschists an...

This paper deals with formulation of constitutive relations describing the time-dependent deformation in sedimentary rocks. In contrast to classical viscoplasticity, the creep effects are attributed here to a progressive evolution of material microstructure. First, an internal variable monitoring the degradation process is introduced followed by presentation of a general framework of chemo-plas...

A constitutive theory is proposed for FRP laminated composite materials that is designed to account for both temperature and strain rate dependent response, such as would occur during, and after, exposure to the elevated temperatures due to fire. The theory is physically based, and in particular, is based on a kinematical framework fixed on the fabric laminates; full accounting of laminate reor...

Laboratory studies on deformation of olivine in response to applied stress suggest two distinct deformation mechanisms in the earth’s upper mantle: diffusion creep through diffusion of atoms along grain boundaries and dislocation creep by slipping along crystallographic glide planes. Each mechanism has very different and important consequences on the dynamical evolution of the mantle and the de...
