The development of layered finite elements has facilitated analysis of laminated composite structures. However, the analysis of a structure containing both isotropic and composite materials remains a difficult problem. A methodology has been developed to conduct a ''global-local'' finite element analysis. A ''global'' analysis of the entire structure is conducted at the appropriate loads with the composite portions replaced with an orthotropic material of equivalent materials properties. A ''local'' layered composite analysis is then conducted on the region of interest. The displacement results from the ''global'' analysis are used as loads to the ''local'' analysis. the laminate stresses and strains can then be examined and failure criteria evaluated.

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.

The purpose of this work is to develop global/local finite element models using partial hybrid stress finite elements for stress analysis of laminated composite structures. Based on the composite variational principle, the general formulations of partial hybrid single-layer finite element and multilayer finite element are presented. These formulations can be used to develop a series of partial hybrid finite elements. A 4-node degenerated plate element, an 8-node degenerated plate element, a 3-D, 8-node solid element, a 3-D, 20-node solid element, a 6-node transition element, a 15-node transition element, a multilayer solid element, and a multilayer transition element are presented. The elements developed in this thesis are examined by the, eigenvalue test to detect zero-energy deformation modes and the absence of rigid-body motion capability. The results show that the elements do not have any kinematic deformation modes, and they have a desired capability for rigid-body displacement. In addition, the non-zero eigenvalues of the element stiffness matrices are real and positive. In order to determine the optimal partial stress fields for the partial hybrid elements, a classification method of stress modes is presented. The method can be used to classify stress modes, select optimal stress modes, and set up an assumed stress matrix for a hybrid element. Also, the necessary and sufficient condition for avoiding spurious kinematic deformation mode is proposed and the optimal condition of an assumed stress field is presented. A computer program COMSA is developed to implement the partial hybrid finite element method. The Global/Local finite element models are established using plate element, solid element, and transition element. In the thesis, a few numerical examples are presented to verify the accuracy and efficiency of the finite element models. It has been shown that the global/local models using partial hybrid element are efficient and accurate for stress analysis of laminated composites due to the fact that they take advantage of the capacity of both 3-D elements and 2-D elements.

The question of inclusion of local effects in the analysis of structures is currently one of prime importance for engineering design. The classical computational approaches are not readily adapted to take local effects into account and appropriate treatments are therefore necessary. Providing an introduction to and survey of the specific computational methods, this book contains 16 papers, most of which were presented at the EUROMECH Colloquium `Inclusion of Local Effects in the Analysis of Structures', held in France in 1984. The book begins with the various theories which allow the separation and determination of local and global effects. The next group of papers discuss edge effects for composite structures. The third part comprises two papers concerning dynamic problems and points the way towards non-conventional local effects in structural mechanics. The last part deals with general numerical methods, especially for effects due to large local variations of geometry.

The papers contained herein were presented at the Fourth International Conference on Composite Structures (ICCS/4) held at Paisley ColIege of Technology, Scotland in July 1987. The Conference was organised and sponsored by Paisley College of Technology. It was co-sponsored by the Scottish Development Agency, the National Engineering Laboratory, the US Air Force European Office of Aerospace Research and Development and the US Army Research, Development and Standardisation Group- UK. It forms a natural and ongoing progression from the highly successful First, Second and Third International Conferences on Composite Structures (ICCS/I, ICCS/2 and ICCS/3) held at Paisley in 1981, 1983 and 1985 respectively. There is little doubt that composite materials are rightfulIy claiming a prominent role in structural engineering in the widest sense. Moreover, the range and variety of useful composites has expanded to a level inconceivable a decade ago. However, it is also true that this increasing utilisation has generated an enhanced awareness of the manifold factors which dictate the integrity of composite structures. This is indeed a healthy attitude to a relatively new dimension in structural engineering which will have an increasingly dominant role as the century progresses. Both the diversity of application of composites in structural engineering and the endeavours which wilI ensure their fitness for purpose are reflected herein.
