A complete and comprehensive theory of failure is developed for homogeneous and isotropic materials. The full range of materials types are covered from very ductile metals to extremely brittle glasses and minerals. This book, which is destined to become a classic in the discipline of the mechanics of solids, gives detailed derivations and solid scientific evaluations of failure criteria of various classes of materials. [] Professor Christensen joins the ranks of luminaries such as Professors Rodney Hill and Daniel Drucker as a legend in solid mechanics, through this excellent book.
