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.

Clarence L. “Kelly” Johnson led the design of such crucial aircraft as the P-38 and Constellation, but he will be more remembered for the U-2 and SR-71 spy planes. His extraordinary leadership of the Lockheed “Skunk Works” cemented his reputation as a legendary figure in American aerospace management. From the Trade Paperback edition.

Twenty-five years after Jesus’ Son, a haunting new collection of short stories on mortality and transcendence, from National Book Award winner and two-time Pulitzer Prize finalist Denis Johnson The Largesse of the Sea Maiden is the long-awaited new story collection from Denis Johnson. Written in the luminous prose that made him one of the most beloved and important writers of his generation, this collection finds Johnson in new territory, contemplating the ghosts of the past and the elusive and unexpected ways the mysteries of the universe assert themselves. Finished shortly before Johnson’s death, this collection is the last word from a writer whose work will live on for many years to come. Advance praise for The Largesse of the Sea Maiden “Mesmerizing . . . psychologically revelatory, spiritually inquisitive, and grimly funny stories . . . Johnson will be remembered and revered as an incisive storyteller fluent in the comedy and tragedy of human confusion and the transcendence of compassion.”—Booklist (starred review) “American literature suffered a serious loss with Johnson’s death. These final stories underscore what we’ll miss. . . . Johnson is best known for his writing about hard-luck cases—alcoholics, thieves, world-weary soldiers. But this final collection ranges up and down the class ladder; for Johnson, a sense of mortality and a struggle to make sense of our lives knew no demographic boundaries.”—Kirkus Reviews (starred review) “An instant classic . . . A masterpiece of deep humanity and astonishing prose . . . It’s filled with Johnson's unparalleled ability to inject humor, profundity, and beauty—often all three—into the dark and the mundane alike. These characters have been pushed toward the edge; through their searches for meaning or clawing just to hold on to life, Johnson is able to articulate what it means to be alive, and to have hope.”—Publishers Weekly (starred review)

The world’s most revered and eloquent interpreter of evolutionary ideas offers here a work of explanatory force unprecedented in our time—a landmark publication, both for its historical sweep and for its scientific vision. With characteristic attention to detail, Stephen Jay Gould first describes the content and discusses the history and origins of the three core commitments of classical Darwinism: that natural selection works on organisms, not genes or species; that it is almost exclusively the mechanism of adaptive evolutionary change; and that these changes are incremental, not drastic. Next, he examines the three critiques that currently challenge this classic Darwinian edifice: that selection operates on multiple levels, from the gene to the group; that evolution proceeds by a variety of mechanisms, not just natural selection; and that causes operating at broader scales, including catastrophes, have figured prominently in the course of evolution. Then, in a stunning tour de force that will likely stimulate discussion and debate for decades, Gould proposes his own system for integrating these classical commitments and contemporary critiques into a new structure of evolutionary thought. In 2001 the Library of Congress named Stephen Jay Gould one of America’s eighty-three Living Legends—people who embody the “quintessentially American ideal of individual creativity, conviction, dedication, and exuberance.” Each of these qualities finds full expression in this peerless work, the likes of which the scientific world has not seen—and may not see again—for well over a century.

A compact presentation of the foundations, current state of the art, recent developments and research directions of all essential techniques related to the mechanics of composite materials and structures. Special emphasis is placed on classic and recently developed theories of composite laminated beams, plates and shells, micromechanics, impact and damage analysis, mechanics of textile structural composites, high strain rate testing and non-destructive testing of composite materials and structures. Topics of growing importance are addressed, such as: numerical methods and optimisation, identification and damage monitoring. The latest results are presented on the art of modelling smart composites, optimal design with advanced materials, and industrial applications. Each section of the book is written by internationally recognised experts who have dedicated most of their research work to a particular field. Readership: Postgraduate students, researchers and engineers in the field of composites. Undergraduate students will benefit from the treatment of the foundations of the mechanics of composite materials and structures.
