Understanding the Basics of Nanoindentation and Why It Is Important Contact damage induced brittle fracture is a common problem in the field of brittle solids. In the case of both glass and ceramics—and as it relates to both natural and artificial bio-materials—it has triggered the need for improved fabrication technology and new product development in the industry. The Nanoindentation Technique Is Especially Dedicated to Brittle Materials Nanoindentation of Brittle Solids highlights the science and technology of nanoindentation related to brittle materials, and considers the applicability of the nanoindentation technique. This book provides a thorough understanding of basic contact induced deformation mechanisms, damage initiation, and growth mechanisms. Starting from the basics of contact mechanics and nanoindentation, it considers contact mechanics, addresses contact issues in brittle solids, and explores the concepts of hardness and elastic modulus of a material. It examines a variety of brittle solids and deciphers the physics of deformation and fracture at scale lengths compatible with the microstructural unit block. Discusses nanoindentation data analysis methods and various nanoindentation techniques Includes nanoindentation results from the authors’ recent research on natural biomaterials like tooth, bone, and fish scale materials Considers the nanoindentation response if contact is made too quickly in glass Explores energy issues related to the nanoindentation of glass Describes the nanoindentation response of a coarse grain alumina Examines nanoindentation on microplasma sprayed hydroxyapatite coatings Nanoindentation of Brittle Solids provides a brief history of indentation, and explores the science and technology of nanoindentation related to brittle materials. It also offers an in-depth discussion of indentation size effect; the evolution of shear induced deformation during indentation and scratches, and includes a collection of related research works.

Mechanical engineering, an engineering discipline borne of the needs of the industrial revolution, is once again asked to do its substantial share in the call for industrial renewal. The general call is urgent as we face profound issues of productivity and competitiveness that require engineering solutions, among others. The Mechanical Engineering Series features graduate texts and research monographs intended to address the need for information in contemporary areas of mechanical engineering. The series is conceived as a comprehensive one that covers a broad range of concentrations important to mechanical engineering graduate education and research. We are fortunate to have a distinguished roster of consulting editors on the advisory board, each an expert in one of the areas of concentration. The names of the consulting editors are listed on the facing page of this volume. The areas of concentration are: applied mechanics; biomechanics; computational mechanics; dynamic systems and control; energetics; mechanics of materials; processing; thermal science; and tribology.

Indentation techniques have become widely used in the characterization of brittle solids due to their simplicity, cost effectiveness, rapidness, and maybe most importantly, the indenter itself can be used as a mechanical microprobe in thin films, interfaces, grain boundaries, and nanocomposites. The papers in these proceedings cover measurement techniques, reliability of, and problems associated with this testing method. Also included is the application of nano-indentation technique, as a new frontier in brittle solids characterization, e.g., thin film and nano-composite materials.

There has been enormous growth in the use of medical implants. However, in the case of hip replacement, loosening of metallic prosthesis fixed with polymethylmethylacrylate bone cement has resulted in painstaking revision surgery, which is a major problem for the patient, surgeon, and biomedical technology itself. In fact, global recognition of this problem led to the development of cementless fixation through the novel introduction of a bioactive hydroxyapatite (HAp) coating on biomedical-grade metallic implants. Since then, a wide variety of coating methods have evolved to make the HAp coatings on metallic implants more reliable. Microplasma Sprayed Hydroxyapatite Coatings discusses plasma spraying and other related HAp coating techniques, focusing on the pros and cons of macroplasma sprayed (MAPS)- and microplasma sprayed (MIPS)-HAp coatings. The book begins by explaining what a biomaterial really is, what the frequently used term biocompatibility stands for, and why it is so important for biomaterials to be biocompatible. It then: Examines the structural, chemical, macromechanical, micro/nanomechanical, and tribological properties and residual stress of HAp coatings Evaluates the efficacies under simulated body fluid immersion for MAPS- and MIPS-HAp coatings developed on biomedical implant-grade SS316L substrates Offers a comprehensive survey of state-of-the-art in vivo studies of MIPS-HAp coatings, presenting the results of pioneering research related to bone defect fixation Shedding light on the future scope and possibilities of MIPS-HAp coatings, Microplasma Sprayed Hydroxyapatite Coatings provides a valuable reference for students, researchers, and practitioners of biomedical engineering and materials science.

This volume, the second in a new series from MRS, highlights the maturation in the field of nanoindentation and nanotribology. In comparison to the first volume, the emphasis here is considerably less on techniques and analysis for depth-sensing indentation and more on the use of indentation techniques to solve materials problems and understand materials behavior. Although technique development continues to be central to this field, accepted procedures for instrument and probe calibration, and deconvolution of nm-scale load-displacement data in terms of underlying materials properties, are now in wide use. This is particularly evident by the broad participation of researchers from university, industry and government laboratories. Presentations demonstrating extensions of nanoindentation methods include viscoelastic contacts, hard coatings on soft substrates, three-dimensional finite element models, dissipated energy-based analyses, the use of loading and unloading slopes, measurement of residual stresses, and direct comparison of indentation-derived properties with those from bulk tests. The positive response to the symposium, reflected in the range of new materials and methods included in the proceedings, suggests that nanoindentation and nanotribological techniques have a bright future.

Subduction zones, one of the three types of plate boundaries, return Earth's surface to its deep interior. Because subduction zones are gently inclined at shallow depths and depress Earth's temperature gradient, they have the largest seismogenic area of any plate boundary. Consequently, subduction zones generate Earth's largest earthquakes and most destructive tsunamis. As tragically demonstrated by the Sumatra earthquake and tsunami of December 2004, these events often impact densely populated coastal areas and cause large numbers of fatalities. While scientists have a general understanding of the seismogenic zone, many critical details remain obscure. This volume attempts to answer such fundamental concerns as why some interplate subduction earthquakes are relatively modest in rupture length (greater than 100 km) while others, such as the great (M greater than 9) 1960 Chile, 1964 Alaska, and 2004 Sumatra events, rupture along 1000 km or more. Contributors also address why certain subduction zones are fully locked, accumulating elastic strain at essentially the full plate convergence rate, while others appear to be only partially coupled or even freely slipping; whether these locking patterns persist through the seismic cycle; and what is the role of sediments and fluids on the incoming plate. Nineteen papers written by experts in a variety of fields review the most current lab, field, and theoretical research on the origins and mechanics of subduction zone earthquakes and suggest further areas of exploration. They consider the composition of incoming plates, laboratory studies concerning sediment evolution during subduction and fault frictional properties, seismic and geodetic studies, and regional scale deformation. The forces behind subduction zone earthquakes are of increasing environmental and societal importance.
