Adhesively-bonded joints provide many advantages over conventional mechanical fasteners and are increasingly receiving attention as an alternative to mechanical joints in engineering applications. The traditional fasteners usually result in the cutting of fibers and hence the introduction of stress concentrations, both of which reduce structural integrity. By contrast, bonded joints are more continuous and have potential advantages of strength-to-weight ratio, design flexibility, and ease of fabrication. This book provides an overview of available analytical methods as well as numerical methods.

The state of the art in the stress analysis and strength prediction of adhesively bonded composite joints is presented. A generalized coordinate finite element analysis based on rectangular, cylindrical and wedge solid elements is developed and utilized for the three-dimensional analysis of composite bonded joints. The comparison of results between 2-D and 3-D bonded joint analysis tools are made and their limitations are discussed. Further, the submodeling technique available in the commercial finite element package ABAQUS is explored to study the three-dimensional stress field in the vicinity of joint edges and debond cracks. The series of bolted joint design codes BONJO developed by Lockheed are incorporated into a PC based Bolted and Bonded Joint (BBJ) design methodology. The Bolted and Bonded Joint design tool is made more informative and user-friendly through the use of Windows 95TM based Graphic User Interfaces (GUIs) fully integrated with a material database and on-line help.

The book comprehensively charts a way for industry to employ adhesively bonded joints to make systems more efficient and cost-effective Adhesively bonded systems have found applications in a wide spectrum of industries (e.g., aerospace, electronics, construction, ship building, biomedical, etc.) for a variety of purposes. Emerging adhesive materials with improved mechanical properties have allowed adhesion strength approaching that of the bonded materials themselves. Due to advances in adhesive materials and the many potential merits that adhesive bonding offers, adhesive bonding has replaced other joining methods in many applications. Containing nine articles written by world-renowned experts, the book deals with the advances in theoretical and computational modeling as well as the design and experimental aspects of adhesively bonded structural systems. Stress analysis and strength prediction of adhesively bonded structural systems, considering a range of material models under a variety of loading conditions, are discussed. Finite element modeling using macro-elements is elaborated on. Recent developments in modeling and experimental aspects of bonded systems with graded adhesive layers and dual adhesives are described. Simulation of progressive damage in bonded joints is addressed. A novel vibration-based approach to detect disbonding and delamination in composite joints is also discussed. Readership The book is central to a range of engineers including mechanical, reliability, construction and surface engineers as well as materials scientists who are engaged in the mechanics of structural adhesive joints. Industries that will use this book include aerospace, electronics, biomedical, automotive, ship building, and construction.
