Available in PDF, EPUB and Kindle. Book excerpt: Airframes are subjected to various loads from mechanical to thermal loads during operations of aircrafts. Sections made by using GLARE are affected by this loads,in terms of their mechanical properties. Adetailed understanding of the behaviour of these laminates is necessary for further improvement of their performance and durability. With the increase in complexity of structures and material systems, the need for powerful design tools becomes evident.Numerical simulation is a very powerful tool to investigate the behaviour of materials and structures. In this thesis, the mechanical behaviour of fiber metal laminates has been characterized via numerical analysis.This work was carried out focusing on thenumerical simulation of the structures made out of GLARE, using PLCd finite element code,an FE code, developed by the RMEE (Department of Structures and Strength of Materials, UPC) and CIMNE (International Center for Numerical Methods in Engineering) which allows the accurate analysis of elastic and plastic behaviour of materials under various loads. Several numerical tests have been simulated.Special attention has been placed on describing the Serial/Parallel mixing theory and its scope to deal with thenumerical simulation.An iterative learning process has been carried out in order to get the enough knowledge to deal with the simulation of the experimental testscarried out in other literaturesources. The preliminary stages have been done with aim ofgaining experience regarding the mesh sizes,parameter inputsand the differences obtained with different parametersin terms of numerical results accuracy and also computational time costs.Afterwards, simulations havebeen donein order to learn how to simulate aluminium composite laminates in the linear and non-linear range, as well as to fully understand the performance of the SPtheory. The simulations conducted and the results analysedhave allowed to obtain an excellent understanding on the mechanical performance of both aluminium and composite materials, the complexities associated with material non-linearities, and the requirements of non-linear finite element methods. This work presents all these simulations as well as the conclusions obtained from each one of them.Hence, the SP mixing theory, in addition with an appropriate constitutive equations, has showed that the approach is capable ofsimulatingloads and predict the materialnon-linear behaviourof the composite components.The concept of continuum damage mechanics is used, with a damage modelfor fiber and matrix.

Book excerpt: Glare is the name given to a new material for aircraft structures developed at Delft University in the Netherlands. It consists of thin aluminium layers bonded together by adhesive containing embedded fibres and is very resistant to fatigue. This book gives the inside story of how the development of Glare took place. It took more than two decades from the first tests in Delft to the major breakthrough following the decision of Airbus to apply the material on the A380 super-jumbo. This success was achieved by a small group of people inspired by professor Boud Vogelesang, people who kept believing in the material and fought against all obstacles during the years. This book tells the story of the ups and downs and the final success of their efforts.

This book was released on 2012-06-23 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fatigue of the pressurized fuselages of transport aircraft is a significant problem all builders and users of aircraft have to cope with for reasons associated with assuring a sufficient lifetime and safety, and formulating adequate inspection procedures. These aspects are all addressed in various formal protocols for creating and maintaining airworthiness, including damage tolerance considerations. In most transport aircraft, fatigue occurs in lap joints, sometimes leading to circumstances that threaten safety in critical ways. The problem of fatigue of lap joints has been considerably enlarged by the goal of extending aircraft lifetimes. Fatigue of riveted lap joints between aluminium alloy sheets, typical of the pressurized aircraft fuselage, is the major topic of the present book. The richly illustrated and well-structured chapters treat subjects such as: structural design solutions and loading conditions for fuselage skin joints; relevance of laboratory test results for simple lap joint specimens to riveted joints in a real structure; effect of various production and design related variables on the riveted joint fatigue behaviour; analytical and experimental results on load transmission in mechanically fastened lap joints; theoretical and experimental analysis of secondary bending and its implications for riveted joint fatigue performance; nucleation and shape development of fatigue cracks in riveted longitudinal lap joints; overview of experimental investigations into the multi-site damage for full scale fuselage panels and riveted lap joint specimens; fatigue crack growth and fatigue life prediction methodology for riveted lap joints; residual strength predictions for riveted lap joints in a fuselage structure. The major issues of each chapter are recapitulated in the last section.

Available in PDF, EPUB and Kindle. Book excerpt: Shells are basic structural elements of modern technology and everyday life. Examples of shell structures in technology include automobile bodies, water and oil tanks, pipelines, silos, wind turbine towers, and nanotubes. Nature is full of living shells such as leaves of trees, blooming flowers, seashells, cell membranes or wings of insects. In the human body arteries, the eye shell, the diaphragm, the skin and the pericardium are all shells as well. Shell Structures: Theory and Applications, Volume 4 contains 132 contributions presented at the 11th Conference on Shell Structures: Theory and Applications (Gdansk, Poland, 11-13 October 2017). The papers reflect a wide spectrum of scientific and engineering problems from theoretical modelling through strength, stability and dynamic behaviour, numerical analyses, biomechanic applications up to engineering design of shell structures. Shell Structures: Theory and Applications, Volume 4 will be of interest to academics, researchers, designers and engineers dealing with modelling and analyses of shell structures. It may also provide supplementary reading to graduate students in Civil, Mechanical, Naval and Aerospace Engineering.
