Available in PDF, EPUB and Kindle. Book excerpt: This report presents the results of tests of the ice friction coefficient mu sub k carried out during the May 1984 expedition of the F.S. Polarstern off the coast of Labrador. The test surfaces were Inerta-160-coated steel plates and bare steel plates, hand roughened and sandblasted. The main findings of the studies were: 1) columnar and granular sea ice showed no significant differences in friction coefficient; 2) for columnar ice, mu sub k was independent of ice crystal orientation with respect to test surface; 3) mu sub k was independent of normal pressure applied on ice sample; 4) mu sub k initially decreased with increasing relative velocity between the ice sample and the test surface and reached a steady value at higher speeds; 5) mu sub k increased with increasing surface roughness; 6) a wetting surface exhibited a higher friction coefficient than a non-wetting surface of the same or even higher roughness average.

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.

Book Synopsis Level Ice Breaking by a Simple Wedge by : Jean-Claude Tatinclaux
Download or read book Level Ice Breaking by a Simple Wedge written by Jean-Claude Tatinclaux and published by . This book was released on 1985 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tests in level ice on an idealized icebreaker bow in the shape of a simple wedge were conducted in the test basin. The horizontal and vertical forces on the wedge were measured, and floe size distribution in the wake of the wedge was observed. From the force measurements, the ice wedge/hull friction factor was calculated and found to be in general agreement with the friction factor measured in separate friction tests. The ice floe length and ice floe area measured in the current study were found to follow log-normal probability distributions defined by the length average L and area average A and corresponding standard deviations S sub L and S sub A. The results of these tests and other tests conducted at another facility showed that the ratios A/h squared and L/h (A = average floe area, L = average floe length, h = ice thickness) were, for the same type of model ice, directly proportional to the parameter sigma/gamma h (sigma = ice bending strength, gamma = specific weight of water) and sigma/gamma h, respectively, and independent of the velocity and ice strain modulus or ice characteristic length. However, the coefficients of proportionality appear to depend upon the type of model ice used in the tests. The ratios S-sub-L/A were independent of sigma/gamma h but varied with the bow shape and the type of ice. The available field data are not sufficient for meaningful comparison with the laboratory results. (Author).
