Book Description
The purpose of the research presented herein is to correlate structural sealant laboratory test methods with structural test methods for full-scale curtain-wall mockups. Glass panels were adhered around the perimeter of the glass to extruded anodized aluminum frames using multi-component structural silicone sealants. This is considered "four-sided structural silicone glazing." These panels were tested and deflection was recorded at various typical wind load pressures (in the spirit of ASTM E330: Standard Test Method for Structural Performance of Exterior Windows, Doors, Skylights and Curtain Walls by Uniform Static Air Pressure Difference, ASTM International, West Conshohocken, PA, 2014, www.astm.org) during multiple cure times of the adhesives. The data has been compared to ASTM C1135 (Standard Test Method for Determining Tensile Adhesion Properties of Structural Sealants, ASTM International, West Conshohocken, PA, 2011, www.astm.org) specimen testing performed at the same cure times. The goal of the research was to better understand how well ASTM C1135 characterizes sealant behavior; and use the data as a platform to predict the performance of full-scale construction. By validating structural performance with cure time, assurance of the structural silicones' integrity during transportation to the site can be confirmed. This data set also took into consideration the time needed for removal of temporary fasteners during a replacement of broken glazing on an existing structure. A unique observation concluded that temporary fasteners could in fact be removed within 1 day of application depending upon site conditions. Two sealants were considered in the testing: a conventional two-part, 10:1 ratio structural silicone sealant that has been in use in commercial glazing for 30 years and a new 1:1 ratio two-part, structural silicone sealant that is currently available in hand-held packaging.

Book Description
Unmodified, epoxy resins cause certain problems for both the adhesive formulator and end-user. They are often rigid and brittle; hence, impact resistance and peel strength are poor. For decades, Chemist have been vigorously working to minimize these major shortcomings. Based on a popular course sponsored by the Society of Plastics Engineers and written by an authority in the field, this comprehensive text presents a variety of methods to accomplish what up to now has been a formidable task. Beginning with epoxy chemistry, moving on to fillers, filler treatments, and surfactants, and ending with current and future development in formulating Epoxy Adhesives, this rigorous text addressed the problem of improving flexibility, durability and strength by adding chemical groups to the epoxy structure either via the base resin or the curing agent or by adding separate flexibilizing resins to the formulation to create an epoxy-hybrid adhesive.

Book Description
Heat treatment of metallic alloys constitutes an important step within the production process. The heat treatment process itself is considered as a cycle of heating the workpieces to a predetermined temperature, keeping them at this temperature for the time period required, and cooling them to room temperature in an appropriate way. The process of heating and keeping workpieces at the required temperature is now adays weil mastered and mostly automatized. The process of cooling or quenching which determines actually the resulting properties, is handicapped with many physical and technical uncertainties. Good results can already be obtained predominantly by using empirically based practice. But increased demands on the properties of the pro ducts as weIl as demands on safety and environment conditions of the quenching media require efforts to investigate the details of the quenching process and to transfer the results of the research to practical application. Advances in the knowledge about quenching processes have been achieved by modem applied thermodynamics especially by the heat and mass transfer researches; further the application of computer technology was helpful to new approaches in quenching pro cesses. Special emphases has been given to: - The theory of heat transfer and heat exchange intensification during quenching - Wetting kinematics - Residual stresses after quenching - Determination of the quenching intensity - Prediction of microstructural transformation and hardness distribution after quenching, the latter with some limitations.

Book Description
The Handbook of Adhesives and Sealants, 2nd Edition is primarily written to assist all those who have a permanent or temporary interest in adhesives and sealants. For those new to the field, the Handbook will provide a fundamental knowledge base of materials and processes as well as reasons why they work and (more importantly) why they don’t work. To the more experienced reader, the breadth and thoroughness of the Handbook will provide a way to reduce time spent on trial and error development or on searching for the optimal recommended process. For the academic, the Handbook will connect the important theories regarding surface science, polymeric materials, and mechanics with practical products and applications of commercial significance. This edition includes major new sections on radiation curable adhesive, biological and naturally occurring adhesives, inorganic adhesives, role of bulk properties of the adhesive, non-destructive testing, and industrial application methods. A completely new chapter is devoted to adhesives used in various industries such as automobile, electrical / electronic, construction, packaging, aerospace, household do-it-yourself, and medical.

Book Description
Product design significantly influences product cost and quality, as well as market share and profitability of a firm. Design projects often involve many people belonging to different functional areas and in many organizations several design projects may be under way at the same time. Due to this complexity, management of design has given rise to a rich set of research problems in management and engineering. In this volume, design is considered as the planning and specification activity prior to fabrication. Design determines what products will be produced, how they will be produced, and when they will be introduced into the market. The quality of the products and the speed with which they are developed are significantly affected by the design process. The design process by which a product is developed is determined by the managerial and engineering practices, tools and techniques. This book presents engineering and management perspectives on design. Topics covered include: Decomposition of product development projects; Tools and techniques for preliminary evaluation of designs; Interface between design and manufacturing, assembly and distribution; Design information flows, and Determination of the scope, timing and duration of projects, and the allocation of resources.

Book Description
Basic Soil Mechanics has long been established as the standard work on the subject for degree and diploma students of civil engineering and building. The third edition has been fully revised and updated to provide students not only with the basic principles but also with an awareness of state-of-the-art developments in the field. The approach to stress/strain behaviour has been reconsidered in the light of modern educational methods and the chapter on earth pressure has been revised to take account of the long-awaited British Standard BS 8002. The book also gives greater emphasis to design methods and the use of computers. Basic Soil Mechanics is an essential text for BTEC HNC/D and undergraduate degree courses in civil engineering. It will also be a valuable resource for practising engineers engaged in the design and construction of soil-related structures and systems.
