This study analyses different debonding defect scenarios on a multi-layered material composed of carbon fibre- reinforced polymer as a composite coating applied to structural steel, with the aim of applying it to marine structures. The study utilises vibration-based experimental non-destructive diagnostics and numerical simulations to thoroughly examine the debonding extent at four different lengths: 0%, 25%, 75%, and 100% of the...

The formation of pitting is a major problem in most metals, which is caused by extremely localized corrosion that creates small holes in metal and subsequently, it changes into cracks under mechanical load, thermo-mechanical stress, and corrosion process factors. This research aims to study pit to crack transition phenomenon of steel boiler heat tubes under cyclic thermal load, and mathematical modeling...

Line heating is one of the alternative methods of forming metals and this kind of forming uses the heating torch as a source of heat input. During the process, many parameters are considered like the size of the substrate, thickness, cooling method, source power intensity, the travel speed of the power source, the sequence of heating, and so on. It is important to analyze the factors affecting the...
