Pulsed eddy current (PEC) stimulated thermography is proposed as a powerful non-destructive evaluation (NDE) technique, allowing the operator to observe the heating developed from the eddy current distribution in a structure using infrared imaging, detecting defects over a relatively wide area within a short time. Some defects (impact, delamination, disbond or crack) commonly occur in aerospace...

This work exploited the use of electrical impedance tomography (EIT) with one-step difference Gaussian-Newton (GN) algorithm to detect different types damage on unidirectional carbon fibre/epoxy composite laminates. The major challenge concerning implementation EIT materials has do their anisotropy. To assess this issue, study was conducted fibre composites having layup configurations degrees a...

Composites have been in application for the past 3 – 4 decades, but only in the last decade that engineers have been given any serious consideration for its application in civil infrastructure: such as bridges, roads, earthquake retrofitting of buildings etc. In this paper the growth of application of composites in civil infrastructures and some of its implications are discussed. This paper is ...

This paper presents an experimental study for the structural performance of reinforced concrete (RC) exterior beam-column joints rehabilitated using carbon-fiber-reinforced polymer (CFRP). The present experimental program consists of testing 10 half-scale specimens divided into three groups covering three possible defects in addition to an adequately detailed control specimen. The considered de...

Unlike well-investigated polymer-based soft actuators such as gel, Ionic Polymer-Metal Composite, conducting polymer, a CFRP-based polymeric laminate possesses quite distinguished properties. It was previously reported that a CFRP-PVC laminate exhibited two-way deflection in accordance with environmental temperature, but it could not exhibit symmetric deflection because of its asymmetric struct...

This paper presents the shear performance of reinforced concrete (RC) beams with Tsection. Different configurations of externally bonded carbon fiber reinforced polymer (CFRP) sheets were used to strengthen the specimens in shear. The experimental program consisted of six full-scale, simply supported beams. One beam was used as a bench mark and five beams were strengthened using different confi...
