Deformation and damage evolution of a full-scale adhesive joint between a steel bracket and a sandwich panel for Naval Application
'SAGE Publications', 2020Co-Authors: Jaiswal, Pankaj R, Kumar R Iyer, Saeedifar M., Saleh M.a.s.n., Luyckx Geert, W De ,waeleAbstract:The increasing interest for the Application of adhesive joints in Naval superstructures motivates researchers to gain an in-depth understanding of the mechanical behaviour and failure mechanisms of these joints. This work reports on an experimental study of the deformation behaviour and damage evolution of a full-scale multi-material joint using different instrumentation techniques. Adhesively bonded joints of steel to sandwich panel components have been subjected to quasi-static tensile tests during which the global deformation of the joint and local strain distributions were monitored using digital image correlation (DIC). During one particular tensile test, fibre optic Bragg sensors (FBG) were also applied to the specimen’s surface at different locations in order to quantify the evolution of local strains. Additionally, acoustic emission (AE) sensors were installed in order to monitor damage initiation and evolution with increasing levels of imposed deformation. This test showcased adhesive failure at the interface of the steel adherend and the adhesive, while cohesive failure was observed within the adhesive and skin failure at the interface between adhesive and the composite skin of the sandwich panel. The post-mortem observed failures modes were compared to the acoustic events that originated during the test due to damage initiation and propagation within the joint. The evolution of the different sensor signals, i.e. the damage expressed as cumulative AE energy and local strains measured with Bragg sensors and DIC, are mutually compared and acceptable correlation is found.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Structural Integrity & Composite

Integración de una turbina de gas y un motor diesel para aplicación marina
2020Co-Authors: Royo Bono MaríaAbstract:[EN] The design of a marine propulsion system for Naval Application is challenging, since the high-performance requirements to accomplish a certain mission, usually do not agree with an efficient operation. For this reason, the development of alternative propulsion systems, such as the combination of different prime movers emerged. One of the most efficient arrangement is the CODAG configuration, which combines the use of diesel engines and gas turbines. In this way, the operating profile of a particular vessel can be optimised for high performance and low consumption. This project involves the development of a CODAG propulsion system model in order to optimise the operating profile of a specific vessel. The required power for a particular scenario has been obtained using a Matlab code. It integrates the performance of two high speed diesel engines and an aero-derivative gas turbine based on the GE-LM2500. A matching methodology has been generated to couple the prime movers and the vessels propulsive device. In addition, Turbomatch simulations have been executed to understand the influence of ambient temperature on the gas turbine performance and therefore, on the performance of the CODAG propulsion system. In the same way, the degradation of the gas turbine has been analysed. As a result, it has been built a tool that integrates the above-mentioned features capable of assessing the vessel’s fuel consumption for a given operating profile. The developed tool exhibits a great potential to optimise the performance of vessels with a CODAG propulsion system. Depending on the vessel requirements, the optimization could be among a wide range of possibilities. Also, different CODAG configurations, such as adding another gas turbine, or removing one diesel engines can be analysed.Royo Bono, M. (2017).
