Glass Fibre Reinforced Concrete is recent introduction in the field of concrete technology. The present day world is witnessing the construction of very challenging and difficult Civil Engineering Structures. Concrete being the most important and widely used material is called upon to possess very high strength and sufficient workability properties. Concrete the most widely used consrtuction ma...

In present work 2D FE (finite element) analysis of deformation and damage evolution site in fiber reinforced composites are carried out. The fiber cracking point and stresses is simulated in the fibers/matrix interface, using the ANSYS FE software at varying volume fractions. The effect of matrix cracks and the interface strength on the fiber failure is investigated. Multi-fibre model were used...

Early orthodontic interventions are often initiated in the developing dentition to promote favourable developmental changes. Interceptive orthodontic can eliminate or reduce the severity of a developing malocclusion, the complexity of orthodontic treatment, overall treatment time and cost. The safest way to prevent future malocclusions from tooth loss is to place a space maintainer that is effe...

The RNLI has been using composites for the construction of some of its lifeboats since the early 1970s and in the late 1980s a decision was taken to adopt a newer advanced form of composite construction with a view to saving overall structural weight whilst maintaining the requisite structural strength. This paper presents a broad discussion of the history of the use of composites in the RNLI, ...

High strain loading response of high-performance aerospace grade polyether-ether-ketone (PEEK) and toughened epoxy carbon fibre-reinforced composites has been investigated in pre-impregnated laminates having identical fibre volume fraction, i.e. nearly 65%. Tensile cyclic tests have carried out on the with [±45°]8S stacking sequence, order to characterise inelastic (plasticity) parameters for t...

The global tendency to apply sustainable criteria in most of the productive fields and the limited durability and the pathologies that reinforced concrete elements suffer are aspects that explain the increasing necessity of strengthening this type of structures. The evolution of strengthening techniques has consisted in the development of new technologies that ease the application of the soluti...

The paper presents a flexible software (A.C.T.I.V.E.) able to visualize the superellipsoidal glyphs describing the orientation of short fibres during the dynamic process of casting a short fibre reinforced composite in a container. The software is designed to run on the VRUI framework and it features an optional face-tracking to grant a more natural interaction also on standard non-3D displays....

The natural fiber reinforced composites are being used in various fields of applications that are contributing to the replacement of synthetic fibers composites which consists of Boron, glass fiber, carbon fiber etc.. The composite natural fibers are being used due its light weight, higher specific strength and eco friendly natural, non –abrasive which also have economical value. As they are ma...

The bond between concrete and reinforcement bars is very important to develop the composite behaviour of reinforced concrete. Bond strength is influenced by several factors such as bar diameter, cover of concrete over the bar, spacing of bars, transverse reinforcement, grade and confinement of concrete around the bars, aggregates used in concrete, type of bars and coating applied on bars, if an...

The layer removal method is often used for measurement of internal stresses in homogeneous polymeric materials. In order to extend the use of this method to laminated composites certain refinements are needed. These include: (i) use of varying material properties (elastic moduli) through the thickness of the composite plate; (ii) use of geometric non-linear analysis to account for large deforma...
