Integrated non-destructive testing (NDT) method consisting of acoustic emission (AE) and digital image correlation (DIC) was used to monitor evaluate the load-behaviour shear-critical reinforced concrete beams subjected corrosion. Measurement data in forms mechanical load, deflection, surface strain AE signals were processed collectively analysed facilitate interpretation damage development cha...

In this paper we present two new designs of spherical flexure joints, which are the compliant equivalent a traditional ball-and-socket joint. The formed by tetrahedron-shaped elements, each composed three blade flexures with trapezoidal shape, that connected in series without intermediate bodies. This is respect to currently found literature and helps increase range motion. We also planar ( x -...

An enhanced version of the flexure-based microgap rheometer (FMR) is described which enables rheological measurements in steady state shearing flows of bulk fluid samples of PDMS with an absolute gap separation between the shearing surfaces of 100 nm – 100 μm. Alignment of the shearing surfaces to a parallelism better then 10 rad allows us to reliably measure shear stresses at shear rates up to...

A nano-displacement sensing method for micro-opto-electro-mechanical-systems (MOEMS) is proposed. The method is based on a square attice photonic crystal (PC) made of dielectric silicon posts, mounted on a micro mechanical flexure. The flexure is fixed at one end and is free to ove at the other, to enable elastic deformations that, by being transferred to the photonic crystal array, modify its ...

In the quest to obtain a precise set of aircraft attitude parameters the modeling of wing flexure can become an important issue, especially when short baselines are being used. Previous techniques for the estimation of wing flexure have relied on a constrained Least Squares process to determine the displacement at each epoch before the estimation of the attitude parameters. As will be shown in ...

In this article, we propose a Flexure-FET (flexure sensitive field effect transistor) ultrasensitive biosensor that utilizes the nonlinear electromechanical coupling to overcome the fundamental sensitivity limits of classical electrical or mechanical nanoscale biosensors. The stiffness of the suspended gate of Flexure-FET changes with the capture of the target biomolecules, and the correspondin...

Enhancement of the response of reinforced concrete (RC) beams using fiber-reinforced polymer (FRP) reinforcement bars has become a popular structural technique over the past two decades due to the well-known advantages of FRP composites including their high strength-to-weight ratio and excellent corrosion resistance. Thisstudy presents n...

OBJECTIVES To assess the effect of interfacial surface roughness on the flexure strength and fracture mode and origin utilizing an in-vitro assessment of the clinical failure conditions expected for all-ceramic crowns and the connector area of fixed partial dentures (FPDs) using bilayered ceramic specimens tested in bi-axial flexure. METHODS Sets of 20 bilayered composite discs, with core:den...

This work investigates a new error source for angular velocity or attitude-based transfer alignment, which is caused by the coupling influence of dynamic flexure with ship angular motion. Most traditional studies do not consider this coupling error, as they often assume that dynamic flexure and ship angular motion are uncorrelated. However, the correlation between the dynamic flexure and the sh...

Abstract Heat treatment is often required for ultra-high-performance concrete (UHPC) to achieve high strength. To broad its use in construction, the effect of different curing conditions on properties UHPC has been developed many years. The experimental investigation large scale fibre reinforced (UHPFRC) beams limited. In present study, UHPFRC specimens and cured at 20 °C were prepared investig...
