Vibration and Acoustics of Composite Structures Book Excerpt:

Vibration and Acoustics of Composite Structures presents recent advances on the vibration and acoustics of elastic composite structures. It guides the reader into structural modelling and fluid-structure interactions of elastic structures made from fibre-reinforced, sandwich and functionally graded materials. To achieve this goal, the book presents a series of generalized higher-order shear deformable theories for composite straight/curved beams, plates and shells, which is not available in any other book. The book also provides originally proposed frequency and time-domain methods for structural-acoustic analyses of composite structures immersed in light and heavy acoustic fluid. We have attempted explicit and detailed accounting for the physical phenomena treated in the book, as well as their modelling, and the formulation and solution of the mathematical models. Many numerical examples are given to aid physical insight and to provide benchmark computations of vibration and sound radiation of composite structures. The book should be a useful source of information for those scientists who need to develop skills in theoretical and/or numerical modelling in dynamics and acoustics of elastic structures. It will also serve as a profitable source of material for scientists whose research interests lie elsewhere in mechanics and materials. Includes new, general higher-order shear deformation zig-zag theories for composite beams, plates and shells, and the traditional structural theories can be treated as special cases of the zig-zag theories Includes modified variational formulation for vibration analysis of composite beams, plates and shells made of fibre-reinforced and functionally graded materials Covers frequency and time domain methods for structural-acoustic analysis of composite structures immersed in unbounded light and heavy acoustic fluid

Structural Analysis of Composite Wind Turbine Blades Book Excerpt:

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.

Identification of Damage Using Lamb Waves Book Excerpt:

Lamb waves are guided waves that propagate in thin plate or shell structures. There has been a clear increase of interest in using Lamb waves for identifying structural damage, entailing intensive research and development in this field over the past two decades. Now on the verge of maturity for diverse engineering applications, this emerging technique serves as an encouraging candidate for facilitating continuous and automated surveillance of the integrity of engineering structures in a cost-effective manner. In comparison with conventional nondestructive evaluation techniques such as ultrasonic scanning and radiography which have been well developed over half a century, damage identification using Lamb waves is in a stage of burgeoning development, presenting a number of technical challenges in application that need to be addressed and circumvented. It is these two aspects that have encouraged us to write this book, with the intention of consolidating the knowledge and know-how in the field of Lamb-wave-based damage identification, and of promoting widespread attention to mature application of this technique in the practical engineering sphere. This book provides a comprehensive description of key facets of damage identification technique using Lamb waves, based on the authors’ knowledge, comprehension and experience, ranging from fundamental theory through case studies to engineering applications.
