descriptions and discussions of the experimental methods which have been applied. The contents fall into three sections. The first of these is concerned with push-pull testing and consists of chapters 1 to 5. Four of the chapters are about extensometry. Originally, the extensometers used for fatigue testing were developed from those used in creep testing, but they have been adapted to control the strain and to reverse it. A later development is the side loaded extensometer for radial or axial strain measurement. The method of attachment of the extensometer to the specimen, by ridges or knife edges, is fully discussed from the viewpoints of accuracy of strain measurement and the influence on the life of the testpiece. The latter is material sensitive and the choice of form of extensometry depends on the material and type of test; the exact form chosen is usually a compromise. The fifth chapter of this section considers methods of heating the specimens and the systems of gripping necessary for through zero loading. The second section of the book is concerned with more specialised aspects and consists of chapters 6 to 8. This section deals with reverse-bond testing - a cheap way of obtaining long-term tests - and the relationship with equivalent push-pull tests. There is a chapter describing chambers, which have been used to obtain vacuum or gaseous test environments and a chapter reviewing techniques for monitoring the onset of cracking. The final section, in two chapters, deals with the use of micro-computers in fatigue testing. The first of these is a descrition of a system used for collection of data, analysis and presentation of results. The second chapter describes a system which performs similar functions but also controls the test by generating an analogue voltage command signal which is fed to the testing machine. The book, which is well produced at a fair price in hard covers with an index, will be of value to readers interested in high temperature testing in general and fatigue testing in particular, although rotating bend testing is not discussed.
