This book was released on 1996-06-03 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metal forming plasticity is an advanced subject of intensive current research relevant to both materials science and mechanical engineering. It is used for the analysis and modelling of fabrication processes such as forging, extrusion, rolling, wire, and tube drawing. The fundamentals of flow mechanics are explained here before they are applied in a variety of machine-tool design engineering situations. These fundamentals form the basis of all engineering analyses of the plastic flow in metal forming and are essential to all students of engineering. Worked examples showing the variety of metal forming situations and approximately 200 end-of-chapter problems are also included.

This book was released on 2013-04-17 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: The intention of this book is to reveal and discuss some aspects of the metal fo- ing plasticity theory. The modern theory describes deformation of metallic bodies in cold and hot regimes under combined thermal and mechanical loadings. Th- mal and deformation fields appear in metal forming in various forms. A thermal field influences the material properties, modifies the extent of plastic zones, etc. and the deformation of metallic body induces changes in temperature distribution. The thermal effects in metal forming plasticity can be studied at two levels, - pending on whether uncoupled or coupled theories of thermo-plastic response have to be applied. A majority of metal forming processes can be satisfactorily studied within an uncoupled theory. In such an approach the temperature enters the stress-strain relation through the material constants and through the thermal dilatation. The description of thermo-plastic deformation in metal forming is c- ried out on the ground of thermodynamics.

Download or read book Metal Forming and Impact Mechanics written by S. R. Reid and published by Elsevier. This book was released on 2016-07-29 with total page 395 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metal Forming and Impact Mechanics reviews significant developments concerning the mechanics of metal forming and impact. Topics covered include the kinematics of steady plane flows in elastoplastic media; contact zone and friction coefficient in hot-rolling; and plastic deformation of porous materials. Developments in the use of superplastic alloys, the use of metal tubes as impact energy absorbers, and fracturing of explosively loaded solids are also discussed. This book has 18 chapters divided equally between the broad headings of metal forming and impact mechanics. The section on metal forming mechanics includes papers that explore an upper bound approach to metal forming processes; rotary forming of rings under kinematic constraints; and microcomputer programs for rolling and extrolling. The section on impact mechanics examines the use of elementary approximation techniques to study plastic deformation in pulse loaded structures; static and dynamic axial crushing of circular and square tubes; and shear-control fragmentation of explosively loaded steel cylinders. This monograph will be of value to structural and mechanical engineers, metallurgists, and materials scientists and technologists, as well as to those active in the field of solid mechanics.

Available in PDF, EPUB and Kindle. Book excerpt: From the point of view of mechanics, this monograph systematically demonstrates the theory of plastic bending and its engineering applications; most of the contents of the book are based on the authors' research in the past decade. The monograph not only expounds the contributions of the authors to the fundamental theory of plastic bending, but also presents various applications of the theory in sheet metal forming, particularly in the analysis and prediction of springback and wrinkling of strips and plates subjected to bending or stamping. In addition to theoretical modelling, attention has also been paid to the development of related numerical methods; comparisons with experimental results are also presented.

Available in PDF, EPUB and Kindle. Book excerpt: The plastic forming of metals is a branch of technology, in which great progress has been achieved mainly by collecting practical data resulting from long-time experience. The contribution of theoretical analysis to this progress is not significant. The common argument was, that such an analysis is too difficult and often even impossible. However, the constantly increasing significance of coldwork processing in industrial practice and the progress in the automatic control of these processes, demanding a broad knowledge of the influence of various parameters, and also the need to improve the mechanical behaviour of coldworked elements have proved beyond doubt that better understanding of the theory of plastic forming processes is necessary. This general trend has become evident in several recent publications in recent years, even though these represent only the engineering, approximate approach to theoretical analysis. Recent significant progress in the mathematical theory of plasticity allows to build an analysis of plastic forming processes on a more sound basis. In particular there have been developed graphical methods by means of which slip-line and hodograph meshes are constructed for plane strain and axially symmetric problems. These graphical methods yield not only the required forces but also the. mode of plastic deformation, even for very complex problems. Numerical procedures also give good results if the digital computer technique is employed.

This book was released on 1979 with total page 141 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metal-forming processes of extrusion, drawing, ring compression, and closed-die forging were analysed by the rigid-plastic finite-element method. According to the individual problem characteristics, the method was modified in order to deal with the steady-state configurations of the extrusion and drawing problems, the neutral flow point (or region) problems of ring compression, and the complexity in geometric changes of the closed-die forging problems. The present investigation is a complete study of the axisymmetric steady-state extrusion and drawing processes, including multipass extrusion and drawing. Detailed deformation mechanics were revealed, showing the influence of the previous deformation history on the flow pattern in the current pass. To solve the neutral flow problems in ring compression, a variational formulation was developed for the case where the frictional stress is dependent on the relative velocity at the die-workpiece interface. The finite-element solutions of ring compression were then obtained under various friction conditions for several materials. Some of the results were compared with the approximate theoretical solutions and experimental results. It was concluded that this modified finite-element scheme does provide a useful tool for the analysis of neutral flow problems and for industrial applications. The closed-die forging problems are characterized by very complex geometries, large rigid portions, and rapid changes in velocity fields.

Download or read book Superplastic Flow written by K.A. Padmanabhan and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: Superplasticity is the ability of polycrystalline materials under certain conditions to exhibit extreme tensile elongation in a nearly homogeneous/isotropic manner. Historically, this phenomenon was discovered and systematically studied by metallurgists and physicists. They, along with practising engineers, used materials in the superplastic state for materials forming applications. Metallurgists concluded that they had the necessary information on superplasticity and so theoretical studies focussed mostly on understanding the physical and metallurgi cal properties of superplastic materials. Practical applications, in contrast, were led by empirical approaches, rules of thumb and creative design. It has become clear that mathematical models of superplastic deformation as well as analyses for metal working processes that exploit the superplastic state are not adequate. A systematic approach based on the methods of mechanics of solids is likely to prove useful in improving the situation. The present book aims at the following. 1. Outline briefly the techniques of mechanics of solids, particularly as it applies to strain rate sensitive materials. 2. Assess the present level of investigations on the mechanical behaviour of superplastics. 3. Formulate the main issues and challenges in mechanics ofsuperplasticity. 4. Analyse the mathematical models/constitutive equations for superplastic flow from the viewpoint of mechanics. 5. Review the models of superplastic metal working processes. 6. Indicate with examples new results that may be obtained using the methods of mechanics of solids.
