Fracture: An Advanced Treatise, Volume VII: Fracture of Nonmetals and Composites examines the fracture of nonmetals and composites. The text of this treatise has been designed so that the reader may acquire pertinent information by self-study. Most chapters have been written in detail and, insofar as possible, have been made to fill a significant gap by also providing, when appropriate, the details of complicated and involved mathematical derivations in appendixes. Whenever possible, only a level of college calculus on the part of the reader has been assumed. Numerical examples showing the engineering applications have been included; also, photographs and drawings have been greatly utilized. The book opens with a review of the fracture behavior of glass. This is followed by separate chapters on the fracture of polymeric glasses; mechanics of the fracture process in rock, with emphasis on the engineering viewpoint; the fracture behavior of simple, single-phase ceramics; and empirical information about, and our level of understanding of, fracture in polycrystalline ceramics. Subsequent chapters deal with the fracture of elastomers; molecular mechanical aspects of the isothermal rupture of elastomers; failure mechanics of fibrous composites; fracture mechanics of composites; fracture and healing of compact bones; and fracture of two-phase alloys; and fracture of lake ice and sea ice.
