During a critical examination of the reliability and the service life, mechanical behaviour of stressed cable samples for overhead transmission lines was analyzed. Initially, the elastic properties, strength, and creep behaviour were compared with those of non-stranded wires. After having investigated the stressing mechanism, suitable methods could be developed for analyzing the deleterious effects of aeolian vibrations. Evaluation of the damping properties was improved by using mechano-electrical analogue techniques. Hints for improved reliability in constructing new systems are given. Detailed description of surface damage, fracture and wear of metal strands in cables.

In contrast to other volumes of this series, this issue contains only four papers on “lubrication of Machines”. Nearly half the volume is devoted to a detailed survey of hydrodynamic and elastohydrodynamic (or “elastorheological”) lubrication; about zoo,& of the work reviewed was originally published in Russian. Three other papers deal with the lubrication of bearings, gears and Literature” published in rg6r has been added. related topics. A bibliography on “Lubrication

This volume again contains approximately twelve contributions on the behaviour of metals and plastics in friction couples. The bibliography on Russian and foreign literature covers the year 1961. The only difference from earlier issues is that some of these papers were also published in English in 1965. A cover-to-cover translation therefore seems to become less urgent.

This collective volume edited by M. M. Khruschov and his associates contains more than thirty contributions of varying length. The first group of five papers deals with the theory of hardness as related to atomic structure. The second section deals in some detail with instrumentation. The remaining papers, about half of the book, describe applications of microhardness measurements on materials ranging from common metals to semiconductors. The impression is gained that the techniques used in research and production engineering in the Soviet Union are-as should be the case-quite similar to those in other countries.

1964, 387 pp.
The contents of this important book are not related at all to problems of wear. Professor Bartenev is well-known to readers of this iournal and to polymer scientists. From the literature quoted in his book it is obvious that Professor Bartenev Is aiso familiar with papers published in English. One feels grateful for the fact that the majority of the work from Bartenev’s laboratory has already been made available in English.

1962; translated by ASME,
These cover-to-cover translations prepared with the aid of the National Science Foundation (US) have the same high standard as their predecessors. They are available at an almost nominal price (about $ 8.00) from ASME-Office, 345 East, 47th Street, New York. The contents should be of interest to a large group of engineers, physicists and chemists dealing with wear problems. (For contents (of the original volumes) see Wear, 5 (1962) 502-505.)
