Numerical Methods in Industrial Forming Processes, edited by J.F.T. Pittman, R.D. Wood, J.M. Alexander and O.C. Zienkiewicz, Pineridge Press, Swansea, 1982. ISBN 0-906674-20-4, 808 pages, hard cover, £48.

The technologies of metalworking processes and their numerical modelling have advanced rapidly during the past decade. It is probably true that advances in some of the industrial forming processes would be even more rapid if a more scientific approach were substituted for the empirical and/or trial-and~error procedures c o m m o n l y used in industry. For example, the forging industry has learnt only recently and in a relatively short time how to make complex parts from difficult-to-work materials using computeraided design of dies and simulation of metal flow: it is obviously the computer power that is helping the metalworking industry to push b e y o n d the 'usual' limits and forge that which was once considered unforgeable. Similar examples can be cited in the case of rolling, extrusion, drawing and other metal forming processes. Unfortunately, the power behind the computers does n o t help one very much unless the process itself, with all its variables, is accurately modelled numerically and suitable software developed to communicate with these so-called highly impersonal machines. The volume under review is a permanent contribution to this end. It contains the papers presented at the International Conference on Numerical Methods in Industrial Forming Processes, held at Swansea, during the period 12th-16th July, 1982". The organising committee considers that the papers and k e y n o t e addresses represent a survey o f the state of the art in both research and practice. The editors of this b o o k point o u t that the topic is such that division of the contributions into clearly distinct subject areas is difficult. Indeed, they hope that one of the results of this first conference, devoted entirely to the numerical approach, will be the recognition that many of the numerical techniques discussed are applicable in the analysis of a variety of industrial forming processes. The papers, which have been contributed by international groups in both universities and industry, have been divided into groups comprising k e y n o t e addresses and papers on Bulk Forming, Phase Change and Thermal problems, Constitutive problems, Finite Element Techniques, Polymer Forming, Sheet Forming and Rolling. In this c o n t e x t the reviewer is t e m p t e d to reproduce the paraphrase used by Baron L y t t o n : "Art and Science have their meeting point in m e t h o d " , which has already been used once by the editors of the only other conference (though not in such major scale as the present volume covers) organised to
116 to Forming Processes, Book No. AMD-Vol. 28, ASME, New York, 1978). The volume under review is an excellent source of reference, which has advanced the art and science of industrial forming processes to bring that meeting point much closer. The new developments reported in the proceedings relating to numerical methods and computing as a tool in the field of industrial forming processes, give the reader additionally some ideas of the progress that will be made in this field during the current decade. Finally, a word or two regarding the publishers of this book. Pineridge press is relatively new in the market in comparison with the well-known 'giants'. In such a short time, however, thay have beeen able to produce books of very high quality (such as the present one), which" invariably contain the latest and advanced information: considering the range of books on numerical methods and computing which have been published so far, the reviewer can mention that this publishing house is the world leader on information concerning the aforementioned subject categories.

Industrial Design in Engineering, by C.H. Flurscheim, The Design Council, London, 1983 (and Springer Verlag, Berlin). ISBN 0-85072-123-7, viii + 390 pages, illustrated, hard cover, DM 118,Industrial Design is surely a name conceived by artists to represent a shift in their concept of design towards the requirements of industry; to engineers it seems a mis-nomer, for they must move in the reverse direction to consider the aesthetic sense of form and colour and the topic of psychology. But this is water under the bridge; the name is in general use and no fault of Mr. Flurscheim's. The book seeks " t o provide engineers with a brief picture of the philosophies embraced within the total spectrum of Industrial Design, together with some practical guidance, in order to assist in the marriage of these techniques within engineering." A range of 15 authors have contributed the 18 chapters, but the whole is carefully co-ordinated and cross-referenced and the presentation is of a high standard. Chapter topics include objectives and techniques, ergonomics, form, colour, machine graphics, selection of materials, selection of finishes, design for maintenance, psychological factors, design of control components, safety, models, standardisation, specification for development of products and integration of industrial design and engineering. The final chapter consists of brief reviews of 22 products. Appreciation of form is perhaps the hardest new topic to teach engineers, but the authors avoid dogmatic assertions of right and wrong while identifying and illustrating a number of relevant principles. One example which
