Download or read book Tensile Strength of Frozen Silt written by Zhu Yuanlin and published by . This book was released on 1987 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Constant strain-rate tension tests were conducted on remolded saturated frozen Fairbanks silt at various temperatures, strain rates, and densities. It was found that the critical strain rate of the ductile-brittle transition is not temperature-dependent at temperatures down to -5 C, but varies with density. The peak tensile strength decreases considerable with decreasing strain rate for ductile failure, but it decreases slightly with increasing strain rate for brittle fracture. The failure strain remains almost constant at temperatures lower than about -2 C, but it varies with density and strain rate at -5 C. The initial tangent modulus is independent of strain rate and increases with decreasing temperature and density. Keywords: Frozen mechanics, Frozen soil, Silt, Soil, Strain, Strength.
