It was also shown that when specimens of 2014-T6 aluminum, titanium (6Al-4V), and 4130 steel were fatigued, the surface-layer stress increased. The number of cycles required to initiate a propagating crack was determined. (Modified author abstract).

Available in PDF, EPUB and Kindle. Book excerpt: S AND NUMBER OF FATIGUE CYCLES WAS ESTABLISHED FOR 4130 STEEL (yield strength = 180,000 psi). Confirming the results found for aluminum (2014-T6) and titanium (6Al-4V), fatigue failure occurred when the surface layer stress attained a critical value. The crack propagation rate was measured for 4130 steel at yield strengths of 180,000 and 100,000 psi. The results showed that the SLE treatment improved the crack resistance. Pressure vessels of 4130 steel have been obtained and processed for fatigue testing. Welded specimens of 4130 steel have been made by butt-welding plates and machining out appropriate strips. The microstructure and hardness profile were determined and the specimens readied for test. A four-point fatigue apparatus and associated mechanism for detecting fatigue failure was designed and constructed. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The subject of mechanical behavior has been in the front line of basic studies in engineering curricula for many years. This textbook was written for engineering students with the aim of presenting, in a relatively simple manner, the basic concepts of mechanical behavior in solid materials. A second aim of the book is to guide students in their laboratory experiments by helping them to understand their observations in parallel with the lectures of their various courses; therefore the first chapter of the book is devoted to mechanical testing. Another aim of the book is to provide practicing engineers with basic help to bridge the gap of time that has passed from their graduation up to their actual involvement in engineering work. The book also serves as the basis for more advanced studies and seminars when pursuing courses on a graduate level. The content of this textbook and the topics discussed correspond to courses that are usually taught in universities and colleges all over the world, but with a different and more modern approach. It is however unique by the inclusion of an extensive chapter on mechanical behavior in the micron and submicron/nanometer range. Mechanical deformation phenomena are explained and often related to the presence of dislocations in structures. Many practical illustrations are provided representing various observations encountered in actual structures of particularly technical significance. A comprehensive list of references at the end of each chapter is included to provide a broad basis for further studying the subject.

Book excerpt: Tribology of Polymer Composites: Characterization, Properties, and Applications provides an exhaustive overview of the latest research, trends, applications and future directions of the tribology of polymer composites. Covering novel methods for the synthesis of polymer composites and their properties, the book starts by reviewing the fabrication techniques, wear and frictional properties of polymer composite materials. From there, it features chapters looking at the tribological behavior and properties of specific polymer composite materials such as synthetic fiber-reinforced, cellulose fiber-reinforced, wood fiber, synthetic fiber, mineral fiber-reinforced, and thermosetting composites. Final chapters cover the tribology of polymer nanocomposites and particulate polymer composites and their metal coatings. Applied examples spanning a wide range of industries are emphasized in each chapter. Demonstrates the potential of polymer composites and their applications Covers novel methods for the synthesis of polymer composites and their properties Reviews the fabrication techniques, wear and frictional properties of polymer composite materials

Available in PDF, EPUB and Kindle. Book excerpt: This book covers the most recent advances in the deformation and fracture behaviour of polymer material. It provides deeper insight into related morphology–property correlations of thermoplastics, elastomers and polymer resins. Each chapter of this book gives a comprehensive review of state-of-the-art methods of materials testing and diagnostics, tailored for plastic pipes, films and adhesive systems as well as elastomeric components and others. The investigation of deformation and fracture behaviour using the experimental methods of fracture mechanics has been the subject of intense research during the last decade. In a systematic manner, modern aspects of fracture mechanics in the industrial application of polymers for bridging basic research and industrial development are illustrated by multifarious examples of innovative materials usage. This book will be of value to scientists, engineers and in polymer materials science.

Available in PDF, EPUB and Kindle. Book excerpt: In the early twentieth century, Dr. Irving Langmuir actively studied plasma discharge and surface science. Since then, great progress has been made in the development of applications of discharges and plasmas such as discharge lamps, electric tubes, and arc welding. In relation to studies on space physics and controlled nuclear fusion, plasma physics has greatly advanced. Plasma chemistry has also progressed along with its applications in LSI fabrication technology, the chemical vapor deposition of functional films, and the production of nanomaterials. In the twenty-first century, the further development of applications of plasma physics and plasma chemistry is certainly expected. In this book, 18 chapters on the recent progress in plasma science and technology have been written by active specialists worldwide.
