This book was released on 1973 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: A finite element computer code called WESTES was developed to study the influences of laboratory testing equipment on the states of stress and strain induced in cylindrical specimens of earth media. The code can solve general static, axisymmetric, boundary value problems and is programmed to take an incremental, nonlinear constitutive model called the Variable Moduli Model II. Some of the special features of the code include the ability to simulate cyclic (load/unload/reload) laboratory tests using iterative treatments at the load/unload and unload/reload interfaces and special logic to separately handle loading and unloading in the volumetric and deviatoric stress components as dictated by the constitutive model.

Available in PDF, EPUB and Kindle. Book excerpt: The stress distribution in cylindrical specimens tested in triaxial compression are analyzed using the finite element technique. The effect of various important parameters on the test results are determined and an estimate of the errors involved in assuming a uniform field of stress in the specimen while interpreting test results is given. These parameters include: the slenderness ratio of the specimen; the coefficient of friction and lubrication of the interface between the steel loading plates and the specimen; the thickness and stiffness of the steel plate; the manner in which the steel plates are loaded; the anisotropy of the specimen material; the nonlinearity and plastic flow of the specimen material. Finally, the effect of joints and cracking of rock is also analyzed. To accomplish this study, the two-dimensional, quasi-static finite element code NONLIN was developed to solve problems involving nonlinear, non-homogeneous and anisotropic materials.

Download or read book Nonlinear Stress deformation Analyses of Lake Agassiz Clays Using Finite Element Method written by Palaniappan Valliappan and published by . This book was released on 1974 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: For nonlinear stress-deformation analyses of soils, it is necessary to define the stress-strain behaviour of the soil in quantitative terms, and to develop techniques for incorporating this behaviour in the analyses. The stress-strain behaviour of Lake Agassiz clays was separated into mean normal and deviatoric components and the stresses and strains were interrelated through bulk and shear moduli. Drained isotropic compression tests were used for the evaluation of bulk modulus. A three-parameter stress-strain relationship was used to represent the isotropic stress-strain data. Solutions were obtained for bulk modulus as a function of soil type, void ratio, and imposed stress system. The shear modulus was investigated by drained constant-mean-normal-stress triaxial compression tests. The basic two parameter hyperbolic relationship in a modified form was used to represent the resultant deviatoric stress-strain data and an analytical expression was determined for the shear modulus. The solution for shear modulus was obtained as a function of soil type, previous stress history, failure criterion, void ratio, and imposed stress system. The failure zones and long term uplift capacities predicted for shallow and deep anchors using the finite element method, showed good agreement with those evaluated by using Meyerhof and Adam's theory. The distribution of stresses and displacements along the length of the vertical circular shaft obtained by the finite element analysis were similar to the distributions described by Terzaghi.

Download or read book Analytical Methods in Petroleum Upstream Applications written by Cesar Ovalles and published by CRC Press. This book was released on 2015-04-02 with total page 1351 pages. Available in PDF, EPUB and Kindle. Book excerpt: Effective measurement of the composition and properties of petroleum is essential for its exploration, production, and refining; however, new technologies and methodologies are not adequately documented in much of the current literature. Analytical Methods in Petroleum Upstream Applications explores advances in the analytical methods and instrumentation that allow more accurate determination of the components, classes of compounds, properties, and features of petroleum and its fractions. Recognized experts explore a host of topics, including: A petroleum molecular composition continuity model as a context for other analytical measurements A modern modular sampling system for use in the lab or the process area to collect and control samples for subsequent analysis The importance of oil-in-water measurements and monitoring The chemical and physical properties of heavy oils, their fractions, and products from their upgrading Analytical measurements using gas chromatography and nuclear magnetic resonance (NMR) applications Asphaltene and heavy ends analysis Chemometrics and modeling approaches for understanding petroleum composition and properties to improve upstream, midstream, and downstream operations Due to the renaissance of gas and oil production in North America, interest has grown in analytical methods for a wide range of applications. The understanding provided in this text is designed to help chemists, geologists, and chemical and petroleum engineers make more accurate estimates of the crude value to specific refinery configurations, providing insight into optimum development and extraction schemes.
Download or read book Developments in Ground Control in Mining 1981 2020 written by Syd S. Peng and published by Society for Mining, Metallurgy & Exploration. This book was released on 2022-06-03 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: The best of ground control technology, 40 years in the making. Developments in Ground Control summarizes the objectives, methodology used, and major conclusions reached from papers presented and published in the International Conference on Ground Control in Mining (ICGCM) proceedings from 1981 to 2020. Because the subject areas of the papers published in the proceedings are so broad, ranging from accident training and coal/rock bursts to geology, pillar, multiseam mining, in situ stresses, roof falls, and roof supports to surface subsidence, the papers were grouped into 13 aggregate topics and addressed separately in 13 book chapters by 13 authors from 4 countries. These book chapters are a fresh look at the topics, providing new insights, sourcing older papers, and summarizing data. This is an enormous help for those seeking information on ground control. There were 1,795 papers in the 40 years of ICGCM proceedings in more than 40 ground control topical areas. It would certainly be very time consuming if not impossible to find the right papers of interest in a timely manner. This book makes it easy for interested people to find the progress, application, and achievements of certain techniques from the past 40 years and how they affected the field of ground control and the world mining industry, in particular, the United States. Generally speaking, most researchers tend to favor recent developments when performing a literature search, ignoring or considering old papers outdated. In contrast, over the last 40 years, most research findings for a specific topic in ICGCM received continuing attention for subsequent development or repeated citations if applications were successful.
