Accurate Stress Analysis of Laminated Composite Structures

These Lecture Notes present an overview of a new method suitable for accurate stress analysis of composite, thin-walled laminated components. The method is based on the use of generalised, 2D “smeared” laminate models that, like their conventional counter

PREFACE

Due to their superior specific strength and stiffness characteristics and their adaptability to given structural needs composite laminate materials are not only successful in the fields of aircraft and spacecraft constructions but also gain more spread in the classical fields of mechanical engineering. At the same time the specific demands to the respective composite structures are continuously increasing within each field of application. Correspondingly, a sound understanding of the mechanics of composite laminates becomes important to a continuously increasing group of engineers and with increasing structural demands the methods of mathematical modelling and analysis have to be advanced and have to take into account special effects occurring in connection with the use of composite laminates. The present book reflects the lecture material that was presented in a five-day course on "Modern Trends in Composite Laminates Mechanics" held from July 22 to 26, 2002 at CISM {International Centre for Mechanical Sciences) in Udine, Italy. The aim of the course was to give a clear picture of some new modern trends in composite mechanics and to give a presentation of the current stateof-the-art of the theory and application of composite laminates. To this end the team of lecturers has been chosen in such a way that a good variety of problems and aspects has been covered and treated
