WebAbstract We present the results of tests done to determine the tensile behavior of first-year columnar sea ice over a range of temperatures from −20° to −3°C and strain rates of 10−5 and 10−3s−1. The temperature of a test specimen was dictated by its in-situ location within the sea-ice sheet; samples located near the top of the sea-ice sheet were tested at the … Webthickness ice sheet strength, based on large-scale field tests, are presented. The relationships among bulk sea ice properties, strain rate, and strength are illustrated. A …
Plane-Strain Compressive Strength of Columnar-Grained and Granular-Snow Ice
WebOct 20, 2006 · [1] New experiments have been performed on the brittle compressive failure of columnar-grained, first-year sea ice with the S2 growth texture, harvested from the floating cover on the Arctic Ocean. The ice was proportionally loaded biaxially across the columns at –10°C at 1.5 × 10 −2 s −1; i.e., within the regime of brittle behavior.The … WebA model has been developed for predicting the compressive strength of sea ice sheets (Timco and Frederking, 1990). This model makes use of . 269 the results of numerous … how much salt is in hot sauce
Uniaxial and Plane-Strain Compressive Strength of Model Ice
Webthickness ice sheet strength, based on large-scale field tests, are presented. The relationships among bulk sea ice properties, strain rate, and strength are illustrated. A new constitutive equation was developed for predicting the full-thickness horizontal compressive strength 6c of first-year sea WebFinger rafting develops in an ice cover as a result of a compression regime established within the plane of the ice. As two expanses of sea ice converge toward another, one of them slides smoothly on top of the other (it is overthrusted) along a given distance, resulting in a local increase in ice thickness. The term finger rafting refers to the systematic … WebJan 10, 2024 · A drop off in compressive strength was shown with increasing sea ice porosity. Consequently, a model was developed to depict the combined effects of porosity and strain rate on... how do scammers use your email address
