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: Rheological investigations aim to provide an understanding of the stress-strain-time-temperature relationships for materials; our current understanding results from numerous studies illustrating various approaches to the problem. Although each approach reflects the interests of the investigator, the nature of the materials being studied, and the general state of development of the field at the time, an underlying objective is to relate observed rheological behavior to molecular structure and molecular processes. Toward this end, the two general approaches mentioned by Professor Lazan are important: the phenomenological or macroanalytical, and the solid-state or micromechanistic. (When considering materials such as polymers the latter can be called the molecular theory approach.).
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.

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 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.

This book was released on 1996-06-30 with total page 758 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the edited version of lectures and selected research contributions presented at the NATO ADVANCED STUDY INSTITUTE on MECHANICAL BEHA VI OUR OF MATERIALS AT HIGH TEMPERATURE, held in Sesimbra, Portugal, 12th-22nd September 1995, and organized by 1ST-Lisbon Institute of Technology, PortugaL The Institute was attended by 88 participants, including 15 lecturers from 17 countries including five CP countries. The lecturers were leading scientists and technologists from universities, research institutions and industry. The students were mainly young PhD students and junior academic or research staff with postgraduate qualifications (MSc or PhD). Fourteen students were from the five CP countries. The students presented research papers or posters during the Institute reporting the current progress of their research projects. A total of thirty three lectures, ten research papers and fifty posters were presented. This book does not contain the poster presentations and seven research papers were selected for publication. All the sessions were very active and quite extensive discussions on scientific aspects took place during the Institute. The Advanced Study Institute provided a forum for interaction among scientists and engineers from different areas of research, and young researchers.
Download or read book Creep and Long Term Strength of Metals written by A. M. Lokoshchenko and published by CRC Press. This book was released on 2017-12-14 with total page 621 pages. 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.
