A comprehensive reference with demonstrations of advanced indentation fracture techniques in practical applications to enable better design and more efficient manufacturing Indentation Fracture describes and illustrates advanced applications of indentation fracture in evaluating strength, toughness, and related properties of brittle materials. The book enables better design, manufacture, performance, and reliability of brittle materials as elements in structural components. Emphasizing the practical applications of indentation fracture techniques, especially those of indentation-strength, the book builds on a development of indentation fracture mechanics to demonstrate clear quantitative comparisons and rankings of material fracture behavior, including the behavior of toughened materials. The book includes several case studies linking indentation fracture analyses and measurements to other phenomena including fragmentation cracking, edge chipping and dicing damage, scratching and the Mohs scale, and semiconductor grinding damage. Each case study highlights a different aspect of controlled flaw fracture measurements. The book enables readers to increase the utilization of glasses, ceramics, semiconductors, and similar brittle materials in load-bearing applications by demonstrating experimental indentation techniques to better characterize fracture. A primary focus of the book is demonstration of controlled flaw indentation-strength measurements. Written by an independent scientist with significant research contributions to the field, Indentation Fracture explores a range of topics including: * Brittle fracture fundamentals, discussing equilibrium fractures on uniform and localized loading leading to the Griffith and Roesler equations * Indentation strength variation, covering the effects of contact angle, spherical and flat punch contacts, and contacts in stressed and layered components * Toughened materials strength observations in alumina, silicon nitride, glass ceramics, ferroelastics, and zirconia * Strengths of silicon devices determined by wafer backgrinding, covering linear flaws in silicon, including single and multiple scratches, as well as linear, general, controlled, and grinding flaws Indentation Fracture is an essential reference on the subject for engineers across disciplines, nanotechnologists, geophysicists, and environmental scientists, along with graduate students in materials science and related programs of study.
