Book Description
Measurements of the nonlinear viscoelastic behavior of two adhesives, FM-73 and FM-300, are presented and discussed. Analytical methods to quantify the measurements are given and fitted into a framework of an accelerated testing and analysis procedure. The single integral model used is shown to function well and is analogous to a time-temperature stress-superposition procedure (TTSSP). Advantages and disadvantages of the method accessed with the latter residing primarily with the nature of the creep power law which is utilized.

Book Description
Viscoelasticity is a complicated theorem that is generally used in several aspects of material characterization and modeling of polymers, resins, fiber-reinforced composites, bituminous composites, etc. On the other hand, the heterogeneous nature of composites like asphalt concrete and fiber-reinforced polymers has motivated lots of researchers to investigate the mechanical and rheological properties of these materials. This book mainly consists of the theory and application of viscoelastic materials used for construction. It starts with a comprehensible presentation of the theory of linear and nonlinear viscoelasticity. Wherein, the application of viscoelastic equations and principles on constructional viscoelastic composite materials considering time, temperature, loading rate dependency, and heterogeneity of composite substances is highlighted. The principles and equations of the viscoelasticity theorem are presented in several books, but here it is tried to present them more understandable and straightforwardly. This helps in solving real problems of heterogeneous composite materials, especially those which are used in construction. Moreover, the fundamental experiments for characterizing the elastic and viscoelastic properties of fibrous and bituminous composites are introduced and summarized. Then after, some analytical and empirical formulations for deriving the material properties of composites from the properties of the basic constituents are presented. These are followed by numerical simulation techniques using the finite element method to simulate composite materials.

Book Description
The papers contained herein were presented at the Third International Conference on Composite Structures (ICCS/3) held at Paisley College of Technology, Paisley, Scotland, in September 1985. 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 USAF European Office of Aerospace Research and Development, and the US Army Research, Development and Standard isation Group-UK. It forms a natural and ongoing progression from the highly successful First and Second International Conferences on Composite Structures (ICCS/l and ICCS/2) held at Paisley in 1981 and 1983, respectively. To label composites as rather specialised, sophisticated, space-age structural materials would be to underestimate greatly their wider industrial potential. It is unquestionably true that they will play an increasingly dominant, if not decisive, role in aerospace engineering. Indeed a future aircraft industry without composites as the prime structural materials is inconceivable. However, in an energy-conscious world the high specific weights and stiffnesses of composites make them an attractive proposition in every sphere of transportation engineering. This fact is soundly underlined in one of the Plenary papers contained herein and in one of the sessions devoted to this subject. I t would also be a considerable mistake to interpret composites as simply lightweight alternatives to conventional metallic structural materials.

Book Description
Structural Adhesives Uniquely provides up-to-date and comprehensive information on the topic in an easily-accessible form. A structural adhesive can be described as a high-strength adhesive material that is isotropic in nature and bonds two or more parts together in a load-bearing structure. A structural adhesive material must be capable of transmitting the stress/load without loss of structural integrity within design limits. There are many types of established structural adhesives, including epoxy, urethane, acrylic, silicone, etc. Structural Adhesives comprises nine chapters and is divided into two parts: Part 1, Preparation, Properties, and Characterization; Part 2, Applications. The topics covered include: structural epoxy adhesives; biological reinforcement of epoxies as structural adhesives; marble dust reinforced epoxy structural adhesive composites; characterization of various structural adhesive materials; effects of shear and peel stress distributions on the behavior of structural adhesives; the inelastic response of structural aerospace adhesives; structural reactive acrylic adhesives: their preparation, characterization, properties, and applications; application of structural adhesives in composite connections; and naval applications of structural adhesives. Audience This book should be of much use and interest to adhesionists, materials scientists, adhesive technologists, polymer scientists, and those working in the construction, railway, automotive, aviation, bridge, and shipbuilding industries.

Book Description
Adhesives have been used for thousands of years, but until 100 years ago, the vast majority was from natural products such as bones, skins, fish, milk, and plants. Since about 1900, adhesives based on synthetic polymers have been introduced, and today, there are many industrial uses of adhesives and sealants. It is difficult to imagine a product—in the home, in industry, in transportation, or anywhere else for that matter—that does not use adhesives or sealants in some manner. The Handbook of Adhesion Technology is intended to be the definitive reference in the field of adhesion. Essential information is provided for all those concerned with the adhesion phenomenon. Adhesion is a phenomenon of interest in diverse scientific disciplines and of importance in a wide range of technologies. Therefore, this handbook includes the background science (physics, chemistry and materials science), engineering aspects of adhesion and industry specific applications. It is arranged in a user-friendly format with ten main sections: theory of adhesion, surface treatments, adhesive and sealant materials, testing of adhesive properties, joint design, durability, manufacture, quality control, applications and emerging areas. Each section contains about five chapters written by internationally renowned authors who are authorities in their fields. This book is intended to be a reference for people needing a quick, but authoritative, description of topics in the field of adhesion and the practical use of adhesives and sealants. Scientists and engineers of many different backgrounds who need to have an understanding of various aspects of adhesion technology will find it highly valuable. These will include those working in research or design, as well as others involved with marketing services. Graduate students in materials, processes and manufacturing will also want to consult it.
