This book was released on 2018 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: A simple and efficient methodology has been proposed for characterizing the large strain cyclic simple shear behavior of engineering materials. The proposed methodology includes the use of a modified test specimen coupled with a digital image correlation system to measure the evolution of shear strains during cyclic simple shear deformation. The effectiveness and simplicity of the proposed testing procedure for cyclic simple shear testing lie in the fact that it does not require any custom test apparatus or fixtures to conduct cyclic simple shear tests. The proposed test sample for cyclic simple shear testing makes use of conventional tensile machine with standard grips to conduct the tests. Furthermore, the coupling of the digital image correlation system allows for full-field surface strain mapping, enabling measurement of shear strain evolution throughout the cyclic shear deformation, avoiding any complications associated with shear strain measurements using conventional extensometry techniques. The proposed methodology is successfully applied to characterize the large strain cyclic simple shear behavior of extruded aluminum alloy AA6063 in both T4 and T6 tempered conditions. The obtained cyclic simple shear results are further discussed in light of microstructure evolution during cyclic simple shear deformation.
Download or read book A Cyclic Undrained Simple Shear Testing Method for Soils written by F. Tatsuoka and published by . This book was released on 1989 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: An undrained simple shear testing method for soils using a torsional shear apparatus is described, in which a hollow cylindrical specimen is sheared under plane strain conditions without deforming and rotating all horizontal planes. In this testing method, the simple shear deformation mode is achieved only by several mechanical means without using an automated pressure control system. Typical results of cyclic undrained simple shear tests using uniform cyclic shear stresses on one-dimensionally consolidated saturated sand are presented. A similar undrained testing method with the same inner and outer lateral confining pressures, in which the simple shear condition is satisfied only in an approximated way, is also described. The test results show that the deviation of the stress-strain behavior in the approximate testing method from that under the exact simple shear condition increases as the shear strain increases. However, it was also found that for the purpose of evaluating cyclic undrained simple shear strength values defined by the amplitude of cyclic shear strain, the use of this approximate testing method is justified.

Download or read book Safety and Reliability Methodology and Applications written by Tomasz Nowakowski and published by CRC Press. This book was released on 2014-09-18 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: Within the last fifty years the performance requirements for technical objects and systems were supplemented with: customer expectations (quality), abilities to prevent the loss of the object properties in operation time (reliability and maintainability), protection against the effects of undesirable events (safety and security) and the ability to restore performance (resilience). The need to adapt the operation of complex systems in such an uncertain and volatile environment has caused the necessity to formulate new and well established achievements associated with modeling, testing and evaluation of these properties. The concept of a complex system applies not only to the technical ones but also the infrastructure of major importance for social life such as transportation and logistics systems, buildings, power systems, water distribution systems or health services. Safety and Reliability: Methodology and Applications contains the proceedings of the 24th European Safety and Reliability Conference (ESREL 2014, Wroclaw, Poland, 14-18 September 2014), and discusses theories and methods and their applications in the areas of risk, safety and reliability. The abstracts book (408 pages) + full paper CD-ROM (2496 pages) will be of interest to researchers and practitioners, academics and engineers working in academic, industrial and governmental sectors.

Download or read book Testing Using a Large Scale Cyclic Simple Shear Device written by MI. Amer and published by . This book was released on 1986 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cyclic simple shear testing is considered to be one of the most appropriate ways of reproducing in the laboratory the stresses that would be experienced by an element of soil in level ground subjected to earthquake loading. In the last few years cyclic simple shear testing has been analyzed experimentally and theoretically, and the advantages and limitations of the test presented. The main drawback concerns the lack of complementary shear stresses on the specimen vertical boundary and thereby a selection of the proper specimen size, that is, proper diameter versus height ratio must be carefully considered. The nonuniformity of the strain and stresses in the specimen most likely increases as the specimen diameter versus height ratio decreases. To investigate the specimen size effect on the primary dynamic (cyclic) soil properties, namely, the shear modulus and damping, a large-scale simple shear apparatus was constructed. In it, specimens having diameters from 7.6 to 30.5 cm (3 to 12 in.) and heights from 0.64 to 10.2 cm (1⁄4 to 4 in.) could be tested. Thus a wide range of diameter to height ratios could be obtained. The new testing device, its control system, and the method of preparation and installation of the soil specimens for such a large-scale device are presented and discussed. In addition, a cyclic testing program was conducted on sand and some examples of the data obtained are presented as well.

Download or read book Advanced Experimental Unsaturated Soil Mechanics written by Alessandro Tarantino and published by CRC Press. This book was released on 2005-07-14 with total page 590 pages. Available in PDF, EPUB and Kindle. Book excerpt: The field of experimental unsaturated soil mechanics has grown considerably over the last decade. In the laboratory and in the field, innovative techniques have been introduced into mechanical, hydraulic, and geo-environmental testing. Normally, this information is widely dispersed throughout journals and conference proceedings and it is often difficult to identify suitable equipment and instrumentation for research or professional purposes. In this volume, however, the authors bring together the latest research in laboratory and field testing techniques, and the equipment employed, and examine the current state-of-the-art in a forum devoted solely to experimental unsaturated soil mechanics. The papers published in the proceedings were peer-reviewed by internationally-recognized researchers. The topics tackled by the papers include suction measurement, suction control, mechanical and hydraulic laboratory testing, geo-environmental testing, and field-testing.

Download or read book Advanced Triaxial Testing of Soil and Rock written by Robert T. Donaghe and published by ASTM International. This book was released on 1988 with total page 896 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Although the triaxial compression test is presently the most widely used procedure for determining strength and stress-deformation properties of soils, there have been no books published on triaxial testing since the 1962 second edition of the landmark work The Measurement of Soil Properties in the Triaxial Test by Bishop and Henkel. It is apparent there is a need to document advances made in triaxial testing since publication of Bishop and Henkel's book and to examine the current state of the art in a forum devoted solely to triaxial testing. Because of increasing versatility brought about by recent developments in testing techniques and equipment, it is also important that the geotechnical profession be provided with an up-to-date awareness of potential uses for the triaxial test."--Overview.
