High strain-rate compression tests on ice

WebUniaxial compression tests on cylindrical polycrystalline ice specimens were made to determine the characteristics of the platens. For 21 specimens with ends prepared on a lapping plate to obtain a mirror finish, the measured strength showed a variation of only 13% for length-to-diameter ratios from 0.74 to 2.5, with no systematic trend. WebJul 8, 2024 · The fracture behavior and stress of ice at high strain rates can be determined by combining the SHPB method with high-speed camera observation. The split Hopkinson pressure bar (SHPB) method proposed by Kolsky [ 1, 2] is the most famous impact test to measure the deformation of materials under high strain rates.
