A full factorial design is carried out to investigate the effects of different surface treatments, inclusion silica microparticles and use wash primer on apparent shear strength adherent single-lap aluminium joints. Scanning electron microscopy, energy roughness measurements are performed characterise surface. The results show that decreases joints significantly. cohesive failure main cause red...

This study aims to investigate a friction stir welded joint between steel and aluminum alloy that is employed in maritime applications (i.e., connection the ship over-structures hull or deck). By changing tool rotational direction, advancing retreating side, single lap configuration was studied. Tensile tests were conducted evaluate mechanical resistance surface fracture after preliminary inves...

To improve the dispersion effectiveness of carbon nanotubes (CNTs) in epoxy and adhesion resulted composites on steel substrates, this paper proposed to surface treat CNTs using carboxymethyl cellulose (CMC) epoxy-CNTs composite. The characterizations properties reinforced by CMC treated were then systematically investigated. with three different weight fractions (0.5%, 1%, 2%) CMCs their compo...

Manufacturing and Testing techniques were investigated for the development of efficient joining of composite tubes. The stepped lap joining arrangements were studied. Finite element models were developed using ANSYS finite element code for predicting the stress distribution of the joint under the applied loads. Tubes made of graphite/epoxy were considered. The tubes were tested under both tensi...

BACKGROUND Since accumulating evidence suggests that step rate is strongly associated with running-related injuries, it is important for runners to exercise at an appropriate running cadence. As music tempo has been shown to be capable of impacting exercise performance of repetitive endurance activities, it might also serve as a means to (re)shape running cadence. The aim of this study was to v...
