Available in PDF, EPUB and Kindle. Book excerpt: In the introductory paper of this symposium, Lazan categorizes the possible approaches to the rheological behavior of materials as micromechanistic, macroanalytical, and ad hoc testing. The present paper considers the first two of these three approaches, with reference to the behavior of metals. Particular emphasis is placed on the micromechanistic approach, for although the phenomenological approach has both current value and future potential for engineering purposes, it has become increasingly clear that the processes involved in the inelastic flow of materials are both numerous and complex, and that ultimate understanding will only be achieved as an understanding of the micromechanisms is gained. At the same time it must be recognized that in spite of the long history of experimental and theoretical study, it is only in recent years that much of an insight has been gained into the micromechanisms of the flow of metals and only for the simpler situations--for example, in relatively pure metals. Consequently, for the present, and in fact probably for a long time into the future, the engineer will need to rely on phenomenological correlations.

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this effort was to develop and demonstrate a method of experimentally determining both elastic and plastic strain distributions in metallic materials. This was accomplished by recording minute temperature changes on the surface of the material as it was subjected to various loading conditions. Mathematical relationships relating these changes to the strain in the material was developed and verified. Much of the success of this effort was due to the development of thermocouple attachment and readout technique that recorded minute temperature changes (0.1 degree centigrade) at ten millisecond sample intervals. This small time period sampling assures that heat has not been conducted away from the thermocouple attachment point. The thermocouples consisting of two .13 mm dissimilar metal wires were attached to the surface 0.1 mm apart by discharging a large capacitor grounded to the specimen. The small size permits the mounting of several thermocouples in a small area. The determination of plastic zone outlines is thereby facilitated.
Download or read book Fatigue and Durability of Metals at High Temperatures written by S. S. Manson and published by ASM International. This book was released on 2009 with total page 277 pages. Available in PDF, EPUB and Kindle. Book excerpt: From concept to application, this book describes the method of strain-range partitioning for analyzing time-dependent fatigue. Creep (time-dependent) deformation is first introduced for monotonic and cyclic loading. Multiple chapters then discuss strain-range partitioning in details for multi-axial loading conditions and how different loading permutations can lead to different micro-mechanistic effects. Notably, the total-strain method of strain-range partitioning (SRP) is described, which is a methodology that sees use in several industries. Examples from aerospace illustrate applications, and methods for predicting time-dependent metal fatigue are critiqued.

The most up-to date and comprehensive book in the field, Fundamentals of Creep in Metals and Alloys discusses the fundamentals of time-dependent plasticity or creep plasticity in metals, alloys and metallic compounds. This is the first book of its kind that provides broad coverage of a range of materials not just a sub-group such as metallic compounds, superalloys or crystals. As such it presents the most balanced view of creep for all materials scientists. The theory of all of these phenomena are extensively reviewed and analysed in view of an extensive bibliography that includes the most recent publications in the field. All sections of the book have undergone extensive peer review and therefore the reader can be sure they have access to the most up-to-date research, fully interrogated, from the world’s leading investigators. · Numerous line drawings with consistent format and units allow easy comparison of the behavior of a very wide range of materials· Transmission electron micrographs provide a direct insight in the basic microstructure of metals deforming at high temperatures· Extensive literature review of over 1000 references provide an excellent reference document, and a very balanced discussion
Download or read book A Phenomenological Relation Between Stress Strain Rate and Temperature for Metals at Elevated Temperatures written by Elbridge Z. Stowell and published by . This book was released on 1957 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: A phenomenological relation between stress, strain rate, and temperature is suggested to account for the behavior of polycrystalline metals above the equicohesive temperature. The properties of the metal included in the relation are elasticity, linear thermal expansion, and viscosity. The relation may be integrated under various conditions to provide information on creep rates, creep rupture, stress-strain curves, and rapid-heating curves. It is shown that for one material - 7075-T6 aluminum-alloy sheet - the information yielded by the relation for these four applications agrees reasonably well with test data.

Available in PDF, EPUB and Kindle. Book excerpt: Creep and Creep Rupture of Metals is devoted to the fundamental description of the phenomenon of creep which occurs widely in high-temperature deformation of metals. Special attention is paid to the analysis of long-term strength, which characterizes the stress at which the metal does not fail after a predetermined time. The author details experimental and theoretical results obtained by Soviet and Russian scientists that are absent in currently available publications and demonstrates analytical methods and approaches to achieve long term strength in Metals.

Download or read book Nanomechanics and Micromechanics written by Satya Bir Singh and published by CRC Press. This book was released on 2020-05-01 with total page 181 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume enables readers to interpret and predict the effective mechanical properties of existing and emerging composites through modeling and design. The book addresses that materials and structures with small-scale dimensions do not behave in the same manner as their bulk counterparts. Once the dimensions of the materials are reduced to the micron and sub-micron range, their properties are subject to significant change. Thus, mechanical properties will be varied and will depend on the sample size. In the meantime, due to the large surface-to-volume ration of small structures, deformation mechanisms are subject to change. This volume integrates various approaches in micromechanics and nanomechanics into a unified mathematical framework, complete with coverage of both linear and nonlinear behaviors. It weaves together the basic concepts, mathematical fundamentals, and formulations of micromechanics and nanomechanics into a systemic approach for understanding and modeling the effective material behavior of composite materials. While providing information on recent developments in the mathematical framework of micro- and nanomechanics, the volume addresses highly localized phenomena and a number of interesting applications. It also illustrates application of micromechanical and nanomechanical theory to design novel engineering materials.
