Elementary Mechanics of Plastic Flow in Metal Forming


Book Description

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.

Fundamentals Of Materials Modelling For Metals Processing Technologies: Theories And Applications


Book Description

This book provides a comprehensive introduction to the unique theory developed over years of research on materials and process modelling and its application in metal forming technologies. It starts with the introduction of fundamental theories on the mechanics of materials, computational mechanics and the formulation of unified constitutive equations. Particular attention is paid to elastic-plastic formulations for cold metal forming and unified elastic-viscoplastic constitutive equations for warm/hot metals processing. Damage in metal forming and numerical techniques to solve and determine the unified constitutive equations are also detailed. Examples are given for the application of the unified theories to solve practical problems encountered in metal forming processes. This is particularly useful to predict microstructure evolution in warm/hot metal forming processes. Crystal plasticity theories and modelling techniques with their applications in micro-forming are also introduced in the book.The book is self-contained and unified in presentation. The explanations are highlighted to capture the interest of curious readers and complete enough to provide the necessary background material to further explore/develop new theories and applications.




Metal Forming and Impact Mechanics


Book Description

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.







Metal Forming and the Finite-Element Method


Book Description

The application of computer-aided design and manufacturing techniques is becoming essential in modern metal-forming technology. Thus process modeling for the determination of deformation mechanics has been a major concern in research . In light of these developments, the finite element method--a technique by which an object is decomposed into pieces and treated as isolated, interacting sections--has steadily assumed increased importance. This volume addresses advances in modern metal-forming technology, computer-aided design and engineering, and the finite element method.
