When a text has influenced a large enough audience, for a long enough time, it becomes a classic. We expect that newcomers to the field will enter through this text, and that established professionals will have a well-worn copy in their personal library. Alan Gent's Engineering with Rubber: How to Design Rubber Components is such a classic. It has just been published by Hanser in a 3rd edition, offering a valuable guide to the fundamentals of rubber component mechanical design.
