Plasticity and failure behavior of solids: Memorial volume dedicated to the late Professor Yuriy Nickolaevich Rabotnov / Edition 1

by George C. Sih, A.J. Ishlinsky, S.T. Mileiko

Overview

More than six years ago, several of Rabotnov's close friends and colleagues from the USSR and USA decided to contribute a volume on Plasticity and Failure of Solids in honor of his 70th birthday. The celebration was interrupted unexpectedly by his death on May 13, 1985 at which time another decision was made still to publish the work, but as a memorial volume. As in any field of scientific endeavor, research confronts the scientists with anomalies; our chosen area is no exception. The ways in which failure criteria and plasticity theory are combined can differ widely among the researchers; they will never yield quite the same results. Each of the invited contributors has, therefore, been encouraged to express his views and to expound on his personal opinion. The contributors are free of enumeration from the authority and/or consensus of any scientific society or community. What impedes scientific process is the esoteric tradition of accepting ideas and theories by consensus among members of societies and communities. The absence of such a trend is refreshing; the collaboration between the authors from the USSR and the USA had to be one of the contributing factors. Finally, the editors wish to acknowledge the authors who have made the publication of this volume possible. a. c. Sib S. T. Mileiko AJ.

Editorial Reviews

Researchers from the US and the USSR contribute ten articles reviewing the basic fundamentals and reporting recent developments in the study of the plastic and failure behavior of metals and composites. The main emphasis is on deformation and fracture as occurring in the failure process. Particular attention is given to establishing the relationship between structure, material properties, and the mechanics of fracture. Stresses the fundamentals of plasticity theory, but also describes practical application to illustrate the time-dependent rate effect in material response. Other topics include the failure mechanism in composites, the significance of changes in local strain rates, and the difference between viscous rupture failure and brittle fracture. Annotation c.
