High-strain Zones by Geological Society of London Pdf

This collection of research and review papers addresses the question of structural evolution during deformation to high strains and the physical properties of rocks that have been affected by high-strain zones. The discussions range from natural examples at outcrop to microscopic studies. They include experiments and numerical models based on the active processes in high-strain zones as well as studies on the physical properties of highly strained rocks in the field and laboratory. Specific questions addressed include magnetotelluric imaging of faults, magnetic fabrics, fabric development, seismic properties of highly strained rocks, change of rheology with strain, influence of melt on the localization of deformation, the relationship between deformation and metamorphism as well as new methods in the analysis of deformation. The book is aimed at an interdisciplinary group of readers interested in the effects of high strain in rocks.

Performance of Mechanical Properties of Ultrahigh-Strength Ferrous Steels Related to Strain-Induced Transformation by Koh-ichi Sugimoto Pdf

A variety of topics concerning ultrahigh-strength ferrous steels were collected in this book. At present, most of the ferrous steels are applied to cold sheet parts. However, they may be used as the materials of hot-forged parts in the future, because of the excellent performance of the mechanical properties. It is hoped that many researchers will have an interest in the applications of the ferrous steels to the hot-forging parts.

Proterozoic Orogens of India by T.R.K. Chetty Pdf

Proterozoic Orogens of India: A Critical Window to Gondwana provides a unique opportunity to understand a cross-section of the well-exposed and best-studied part of Earth’s crust and the processes of continental collision. It covers pulses of reworking processes and their impact on magmatism, metamorphism and deformational history of Proterozoic orogens vis-à-vis the supercontinental formation. The details of structural architecture, crustal blocks, shear zone systems, magmatism, metamorphism, geochemical and isotopic signatures, mineralization and tectonic models of all the Proterozoic orogens of India are discussed along with excellent illustrations reflecting the field-based, multi-scale structural and geological data sets. The spatial distribution, geometry, kinematics and transpressional strain of the shear zone systems (mostly suture zones), which are critical to all conceptual models dealing with tectono-metamorphic history of Proterozoic orogens of India, are also covered. The book summarizes and integrates the state-of -the art understanding of the structural architecture, lithological assemblages, petrological, geochemical, geochronological and geophysical aspects of the Proterozoic orogens of India. Includes a much needed state-of-the-art tectonic summary of the voluminous data that has emerged from the Protrozoic orogens of India in the last 2-3 decades Authored by a well-established expert with more than 30 years of experience in the field based, multi-scale structural geological studies of the ancient orogens of India Covers up-to-date reviews and models of Proterozoic orogens developed in the Indian shield over the past 2.5 billion years of Earth history

Explosion, Shock-Wave and High-Strain-Rate Phenomena of Advanced Materials by Kazuyuki Hokamoto Pdf

Materials processing using explosion, shock-wave and high-strain-rate phenomena was developed after WWII, and these explosive forming and welding techniques have since been adopted as an accepted industrial technology. Such extremely high-rate phenomena historically used empirical experiences while the experimental conditions were not well documented due to the difficulties inherent in understanding the real response or behaviour of materials. Based upon the recent development of numerical techniques for analysis and the enriched data available on the behaviour of materials, it is now possible to predict such high-rate phenomena based upon numerical and experimental approaches including optical observation. Explosion, Shock-wave and High-strain-rate Phenomena of Advanced Materials demonstrates the deformation of various materials at high-rate based upon numerical analysis and supported by experimental evidence. The book is recommended for researchers and engineers who would like to learn more about the high-rate effect of materials and those who need to resolve multi-physics problems based on numerical approach. It is also ideal for researchers and engineers interested with explosive and other high-rate processing of materials. Presents numerical techniques on the analysis and enriched data on the behavior of materials based upon a numerical approach Provides case studies to illustrate the various methods discussed Includes mechanical response at high-rates of porous materials

Strain Patterns in Rocks by P. R. Cobbold,W. M. Schwerdtner Pdf

Strain Patterns in Rocks is a selection of papers presented at the international workshop, held in Rennes on May 13-14, 1982. The book presents papers on the techniques of strain measurement; an orthographic analysis of deformation; and the applications of the Mohr circle to inhomogeneous deformation. The text also includes papers on the methods of strain removal; a general transformation to simulate heterogeneous strain states; the significance of isotropic points; and the detection of volume changes. Papers on the analyses of strain discontinuity at interfaces; strain refraction through contrasting layers; and strain patterns in ductile shear zones and at the tips to shear and thrust zones are also considered. The book further includes papers on the natural strain patterns: in mylonite zones, in granites, in Alpine nappes, in linearly anisotropic rocks, in an ice cap and in a boudin model.

Geological Survey of Canada, Current Research (Online) no. 2002-C15 by Sandra E. Johnstone Pdf

This report summarizes observations & structural data collected in the area of the Walker Lake shear zone in the Committee Bay supracrustal belt, central Nunavut. It first reviews the general geology of the metasedimentary & volcanic rocks of the Prince Albert group and the intrusive rocks (tonalite, granite) which were observed in the shear zone. It then describes the three generations of ductile structures that were identified in proximity to the shear zone, and offers some preliminary interpretations regarding the relationship of the shear zone to regional deformation.

Thermodynamic Mechanism of MQL Grinding with Nano Bio-lubricant by Changhe Li Pdf

This book discusses the thermodynamic mechanism of MQL grinding with nano-biological lubricant from the force, heat, surface integrity, and micro-morphology. It makes up the fatal defect of the lack of heat transfer capability of traditional MQL grinding. The machining accuracy, surface quality, especially surface integrity of the workpiece, are significantly improved; at the same time, the service life of the grinding wheel is increased and the working environment is improved. The general scope of the book’s content is the effects of MQL grinding with nano-bio-lubricant on grinding force, thermal mechanism, and surface. It provides a new method of sustainable green grinding for environment-friendly, resource-saving, and energy-efficient utilization and solves the technical bottleneck of the insufficient capacity in MQL heat transfer.

Styles of Continental Contraction by Stefano Mazzoli,Robert W. H. Butler Pdf

"This Special Paper includes a selection of material on the various contractional styles and modes of deformation in internal and external zones, and in deep and shallow parts of orogens. The collection of case studies discusses a broad range of processes and phenomena, including thrust tectonic styles (detachment-dominated vs. thick-skinned, or crustal ramp-dominated) in different subduction and collision orogens; modes and timing of thrust-fold and fabric development; the role of tectonic inversion processes and of strain localization vs. distributed deformation; and syn-convergence extensional deformation (and related tectonic exhumation) in orogens. Case studies are from the Zagros, the Apennines, the Appalachians, the Tasmanides of Eastern Australia, and the Moine Thrust Belt. A review of the main subduction- and collision-related orogens of the world is also provided, including the Alps, the Himalayas, the North American Cordillera, the Andes, the Caledonides of Scotland, the Appalachians, the Alice Springs orogeny in Australia, and the Aleutian and Makran accretionary wedges."--Publisher's website.

Continuum Micromechanics by Dazhi Jiang Pdf

The book integrates theory, numerical methods, and practical applications seamlessly. MATLAB and MathCad programs are provided for readers to master the theory, understand the approach, and to further develop and apply the methods to geological problems. Multiscale and multi-physics investigations of Earth and planetary processes have been an active trend of research in Earth Sciences, thanks to the development of scientific computation and computer software and hardware. Based on the author's research and teaching over the past 15 years, the book stands alone as the first comprehensive text in unifying fundamental continuum micromechanics theory, geometric/kinematic analysis, and applications. The book should appeal to a broad audience of students and researchers, particularly those in the fields of structural geology, tectonics, (natural and experimental) rock deformation, mineral physics and rheology, and numerical modeling of multiscale and coupling processes.
