Abstract:
The critical fracture toughness is a material parameter describing the resistance of a cracked body to further crack extension. It is an important parameter to simulate and predict the break-up behaviour of ice shelves from calving of single icebergs to the disintegration of entire ice shelves over a wide range of length scales. The fracture toughness values are calculated with equations that are derived from an elastic stress analysis. Additionally, an X-ray computer tomography (CT scanner) was used to identify the density as a function of depth. The critical fracture toughness of 91 Antarctic inland ice samples with densities between 840 to 870 kg/m**3 has been determined by applying a four-point-bending technique on single edge v-notched beam samples. The examined ice core was drilled 70m north of Kohnen Station, Dronnning Maud Land (75°00' S, 00°04' E, 2882 m). ** For all details see the full metadata description at "https://doi.pangaea.de/10.1594/PANGAEA.835321"! ** Method of measurements of fracture toughness follows ASTM C1421-01b: Standard test methods for determination of fracture toughness of advanced ceramics at ambient temperature (http://www.astm.org/DATABASE.CART/HISTORICAL/C1421-01B.htm) and ASTM E1820-08: Standard test methods for measurement of fracture toughness (http://www.astm.org/DATABASE.CART/HISTORICAL/E1820-08.htm).Tilgang: unrestrictedEuropean Project for Ice Coring in Antarctica (EPICA)
