This book concerns the development of novel finite elements for the structural analysis of composite beams and blades. The introduction of material damping is also an important aspect of composite structures and it is presented here in terms of their static and dynamic behavior. The book thoroughly presents a new shear beam finite element, which entails new blade section mechanics, capable of predicting structural blade coupling due to composite coupling and/or internal section geometry. Theoretical background is further expanded towards the inclusion of nonlinear structural blade models and damping mechanics for composite structures. The models effectively include geometrically nonlinear terms due to large displacements and rotations, improve the modeling accuracy of very large flexible blades, and enable the modeling of rotational stiffening and buckling, as well as, nonlinear structural coupling. Validation simulations on specimen level study the geometric nonlinearities effect on the modal frequencies and damping values of composite strips of various angle-ply laminations under either tensile or buckling loading. A series of correlation cases between numerical predictions and experimental measurements give credence to the developed nonlinear beam finite element models and underline the essential role of new nonlinear damping and stiffness terms.

Renewable energies constitute excellent solutions to both the increase of energy consumption and environment problems. Among these energies, wind energy is very interesting. Wind energy is the subject of advanced research. In the development of wind turbine, the design of its different structures is very important. It will ensure: the robustness of the system, the energy efficiency, the optimal cost and the high reliability. The use of advanced control technology and new technology products allows bringing the wind energy conversion system in its optimal operating mode. Different strategies of control can be applied on generators, systems relating to blades, etc. in order to extract maximal power from the wind. The goal of this book is to present recent works on design, control and applications in wind energy conversion systems.

The book presents the select peer-reviewed proceedings of the International Conference on Emerging Trends in Design, Manufacturing, Materials and Thermal Sciences (ETDMMT 2020). The contents focus on latest research in product design, CAD/CAE/CFD, robotic systems, neural networks, thermal systems, alternative fuels, propulsion systems, environmental issues related to combustion, autonomous vehicles and alternative energy applications. In addition, the book also covers recent advances in automotive engineering and aerospace technologies. Given the range of contents covered, this book can be useful for students, researchers as well as practicing engineers.

Annotation Over the past three decades, the terminology of composite materials has been well acknowledged by the technical community, and composite materials have been gaining exponential acceptance in a diversity of industries, serving as competitive candidates for traditional structural and functional materials to realize current and future trends imposed on high performance structures. Striking examples of breakthroughs based on utilization of composite materials are increasingly found nowadays in transportation vehicles (aircraft, space shuttle and automobile), civil infrastructure (buildings, bridge and highway barriers), and sporting goods (F1, golf club, sailboat) etc., owing to an improved understanding of their performance characteristics and application potentials, especially innovative, cost-effective manufacturing processes. As the equivalent of ICCM in the Asian-Australasian regions, the Asian-Australasian Association for Composite Materials (AACM) has been playing a vital leading role in the field of composites science and technology since its inception in 1997 in Australia. Following the excellent reputations and traditions of previous ACCMs, ACCM-4 is held in scenic Sydney, Australia, 6-9 July 2004. The theme of ACCM-4, Composites Technologies for 2020, provides a forum to present state-of-the-art achievements and recent advances in composites sciences & technologies, and discuss and identify key and emerging issues for future pursuits. By bringing together leading experts and promising innovators from the research institutions, end-use industries and academia, ACCM-4 intends to facilitate broadband knowledge sharing and identify opportunities for long-term cooperative research and development ventures. The scope of ACCM-4 is broad. It includes, but is not limited to, the following areas: Bi- composites, Ceramic matrix composites, Durability and aging, NDE and SHM Eco-composites, Manufacturing and processing technologies, Industrial applications, Interphases and interfaces, Impact and dynamic response Matrices (polymers, ceramics, and metals), Mechanical and physical properties (fatigue, fracture, micromechanics, viscoelastic behavior, buckling and failure, etc.), Metal matrix composites, Multi-functional composites, Nano-composites, Reinforcements (textiles, strand, and mat), Smart materials and structures, Technology transfer (education, training, etc.)

Acoustic Emission Signal Analysis and Damage Mode Identification of Composite Wind Turbine Blades covers both the underlying theory and various techniques for effective structural monitoring of composite wind turbine blades via acoustic emission signal analysis, helping readers solve critical problems such as noise elimination, defect detection, damage mode identification, and more. Author Pengfei Liu introduces techniques for identifying and analyzing progressive failure under tension, delamination, damage localization, adhesive composite joint failure, and other degradation phenomena, outlining methods such as time-difference, wavelet, machine learning, and more including combined methods. The disadvantages and advantages of using each method are covered as are techniques for different blade-lengths and various blade substructures. Piezoelectric sensors are discussed as is experimental analysis of damage source localization. The book also takes great lengths to let readers know when techniques and concepts discussed can be applied to composite materials and structures beyond just wind turbine blades. - Features fundamental acoustic emission theories and techniques for monitoring the structural integrity of wind turbine blades - Covers sensor arrangements, noise elimination, defect detection, and dominating damage mode identification using acoustic emission techniques - Outlines the wavelet method, the time-difference defect detection method, and damage mode identification techniques using machine learning - Discusses how the techniques covered can be extended and adapted for use in other composite structures under complex loads and in different environments
