Download or read book Kinetic Friction Coefficient of Ice written by Kathryn A. Forland and published by . This book was released on 1985 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study investigates the relative influence of various parameters on the kinetic friction coefficient mu sub k between ice and different surfaces. Friction tests were performed with urea-doped, columnar ice, studying the parameters of normal pressure, velocity, type of material, material roughness, ice orientation, ice hardness and test configuration. Tests were conducted by pulling a sample of ice over a sheet of material and by pulling a sample of material over an ice sheet. An ambient temperature of -1.5 + or - 1 deg C was maintained throughout, and the ice surface hardness was measured using a specially designed apparatus. The results of the friction tests revealed that the behavior of mu sub k with varying velocity was significantly influenced by the test configuration and material roughness. The magnitude of the kinetic friction coefficient was also affected by varying normal pressure, surface roughness and ice hardness. Additional guidelines for standardized ice friction tests and future investigations were recommended.
Download or read book Triaxial Testing of First year Sea Ice written by J. A. Richter-Menge and published by . This book was released on 1986 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents the first series of conventional triaxial tests carried out on columnar first year sea ice samples obtained from the field and tested under controlled laboratory conditions using a large-capacity test machine. A total of 110 horizontal ice samples from Prudhoe Bay, Alaska, were tested on a closed-loop electro-hydraulic test machine at -10 C in unconfined and confined constant-strain-rate compression. The confined tests were conducted in a conventional triaxial cell that maintained a constant ratio between the radial and axial stress to simulate in situ loading conditions. The load ratios used were 0.25, 0.50 and 0.75. The strain rate of each test was constant at 0.01, 0.001, or 0.00001/s. Data are presented on the strength, failure strain and initial tangent modulus of the first year sea ice under these loading conditions. The effects of confining pressure, strain rate and ice structure on the mechanical properties of the ice are examined.

Download or read book Marine Structures Engineering Specialized Applications written by Gregory Tsinker and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 567 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine Structures Engineering is designed to help engineers meet the growing worldwide demand for construction of new ports and the modernization of existing ports and terminals. It provides an authoritative guide to the design, construction, rehabilitation, repair, and maintenance of port and harbor structures. Each chapter is self-contained, allowing readers to access specific information. The Author draws on his extensive experience in offshore structure and port engineering to demonstrate evaluation, rehabilitation, repair, and maintenance of in-service marine structures. Also covered in detail are state-of-the-art approaches to: *marine structures in cold regions, with special attention to the role of ice loads, permafrost, and other ice effects *shiplifts, marine railways, shipways, and dry docks *offshore moorings *floating breakwaters *marinas *structures that protect bridge piers from ship impact. Offering practical information on all aspects of marine structures, this book serves as an indispensable resource to all engineers and professionals involved in design, construction, maintenance, and modernization of ports and harbors.

Download or read book P Ovidius Naso Heroides 1 to 8 written by J. B. Hall and published by Cambridge Scholars Publishing. This book was released on 2023-09-08 with total page 377 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Heroides, or Letters of Heroines, is a collection of twenty-one fictional letters composed by the famous Augustan poet Ovid (43 BC-AD 17/18). It is a widely read work of elegiac poetry which is of special interest to students of gender literature. The poems, which take the form of fifteen letters from heroines to their absent lovers and three pairs of letters to a lover with a reply, have frequently been edited and translated into English in both prose and verse. This volume offers a comprehensive collection of medieval and renaissance readings and modern conjectures for the first eight poems. Such a databank has never even been attempted, let alone accomplished, before now. It is intended to supply the reader with all the information necessary for understanding how the text of the poems has been established.

Download or read book Remote Sensing of Sea Ice in the Northern Sea Route written by Ola M. Johannessen and published by Springer Science & Business Media. This book was released on 2006-11-30 with total page 564 pages. Available in PDF, EPUB and Kindle. Book excerpt: Remote Sensing of Sea Ice in the Northern Sea Route: Studies and Applications initially provides a history of the Northern Sea Route as an important strategic transport route for supporting the northern regions of Russia and cargo transportation between Europe and the Northern Pacific Basin. The authors then describe sea ice conditions in the Eurasian Arctic Seas and, using microwave satellite data, provide a detailed analysis of difficult sea ice conditions. Remote sensing techniques and the basic principles of SAR image formation are described, as well as the major satellite radar systems used for ice studies in the Arctic. The authors take a good look at the use of sensing equipment in experiments, including the ICE WATCH project used for monitoring the Northern Sea Route. The possibilities of using SAR remote sensing for ice navigation in the Northern Sea Route is also detailed, analysing techniques of automatic image processing and interpretation. A study is provided of regional drifting ice, fast ice and river ice in the coastal areas of the Arctic Seas. The book concludes with a review of the practical experience using SAR images for supporting navigation and offshore industrial activity, based on a series of experiments conducted with the Murmansk Shipping Company on board nuclear icebreakers.
