Available in PDF, EPUB and Kindle. Book excerpt: Six construction adhesives and a conventional polyvinyl acetate adhesive were placed under dead load at five stress levels and three temperatures for 2 months. The shear slip was measured after 10, 100, 1,000, 10,000, and 100,000 minutes (70 days) under load. The results show four general types of behavior. Three construction adhesives with crosslinking capability had fair resistance to creep and showed evidence that a creep limit might be reached under moderate dead load and environmental conditions. Two adhesives had very poor creep resistance and failed under moderate dead load and environmental conditions. The sixth adhesive was extremely flexible but with excellent recovery capability. A polyvinyl acetate adhesive was not observed to creep under the low humidity conditions of this study. Adhesives showing evidence of a creep limit may be useful for long-term design loads, but further study of their behavior, especially under varying moisture conditions, is required. (Author).

Book excerpt: Many new adhesives with promising capabilities for use in building construction have time-dependent mechanical properties. Their use has been limited primarily to nonstructural uses due to lack of knowledge about these properties. This study involved developing a useful test method to evaluate the long-term strength and stiffness of flexible adhesives, and exploring some methods of evaluating adhesive time dependency. A versatile test apparatus was developed for this purpose, capable of producing creep, stress relaxation, and creep-rupture strength data. A feature of the apparatus is automated collection of data at selected intervals in a format for computer processing. Strain-time data from preliminary tests of five adhesives were analyzed for fit to algebraic expression, creep-modulus versus time, isochronous stress-strain behavior, and creep-rupture strength. Problems encountered particularly in the equipment development stages are described and suggestions made for future improvements. In spite of the experimental difficulties, useful data were collected and are presented in a format useful to designers of structures that use flexible adhesives in structural joints.

Available in PDF, EPUB and Kindle. Book excerpt: Engineering with polymers is a growing technical field which requires special knowledge. Filling a need, this ready reference brings together the hard-to-get and recently acquired knowledge usually only found scattered in the original literature. At the beginning, the reference introduces plastics as a class of technical materials, gives an overview of their properties, presents plastics processing and its possible influence on the achievable quality of plastic parts. Afterwards, plastics testing is presented as a separate, practical-scientific field of work. The possibilities and fields of application of plastics testing will be discussed. This is followed by a comprehensive treatment of the individual, relevant test areas for the characterization and qualification of plastics and plastic molded parts made from them, with descriptions of the corresponding, practical test methods. A comprehensive index provides easy access to relevant information for successful engineering with plastics and suitable methods for material characterization and for quality assurance and damage analysis of parts. Written by experienced academics and industrial researchers and developers who know the problems of plastics engineers in their daily work - and the solutions - inside out, this book offers first-hand practical knowledge and intensive discussion. The book is aimed at industry, scientists and students involved in plastics and plastic engineering and aims to help them gain the necessary understanding of polymer materials and knowledge of practical testing and evaluation of plastics.
