This book has one single purpose: to present the development of the partial hybrid finite element method for the stress analysis of laminated composite structures. The reason for this presentation is because the authors believe that partial hybrid finite element method is more efficient that the displacement based finite element method for the stress analysis oflaminated composites. In fact, the examples in chapter 5 of this book show that the partial hybrid finite element method is about 5 times more efficient than the displacement based finite element method. Since there is a great need for accurate and efficient calculation of interlaminar stresses for the design using composites, the partial hybrid finite method does provide one possible solution. Hybrid finite method has been in existence since 1964 and a significant amount of work has been done on the topic. However, the authors are not aware of any systematic piece of literature that gives a detailed presentation of the method. Chapters of the displacement finite element method and the evolution 1 and 2 present a sununary of the hybrid finite element method. Hopefully, these two chapters can provide the readers with an appreciation for the difference between the displacement finite element method and the hybrid finite element. It also should prepare the readers for the introduction of partial hybrid finite element method presented in chapter 3.

Hybrid Finite Element Method for Stress Analysis of Laminated Composites presents the development of the partial hybrid finite element method for the stress analysis of laminated composite structures. The authors believe that the partial hybrid finite element method is more efficient than the displacement-based finite element method for the stress analysis of laminated composites. Since there is a great need for accurate and efficient calculation of interlaminar stresses for designs using composites, the partial hybrid finite method does provide one possible solution. Hybrid Finite Element Method for Stress Analysis of Laminated Composites is the culmination of the work of three generations of PhD students in the Concordia Center for Composites. Particular points of interest include: a new ISO function method and classification of stress modes which allow the systematic determination of stress polynomials how the hybrid finite elements and global/local approach allow the stress analysis of laminated composites to be five times more efficient than the displacement finite element method a detailed description of three different types of hybrid finite elements for laminated composites. Hybrid Finite Element Method for Stress Analysis of Laminated Composites will be of interest to researchers and designers of laminated composites as well as finite element method students and programmers of finite element codes.

Based on research papers presented in July 2012 at the Kyoto Institute of Technology, the ninth book in the Canada-Japan Composites Workshop series contains 43 chapters on new ways of fabricating FRP, ceramic, wood, and natural fiber composites and improving their functionality in aerospace, wind energy and civil engineering. Selected subjects covered include: bolted joints, ballistics, recycled matrix materials, pipes, structural health sensing, self-welding, vibration damping, EM shielding, sandwich panels, optical fibers and more. It includes: Effect of Hot-Press Pressure on Mechanical Properties of Unidirectional Jute Spun Yarn Reinforced PLA1; Evaluation of Thin Titanium Films-CFRP Fiber Metal Laminates for Composite Bolted Joints; Evaluation of Fiber/Matrix Interfacial Debonding Behavior Using a Partially Embedded Single Fiber; and, Temperature Effect on Delamination Detection Method in CFRP Laminates Using Mode Conversions of Lamb Waves.
