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.

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.

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.

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.

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.
