摘要: Abstract Experiments have established that the tensile strength of pre-cracked, polycrystalline ice, Ih, when strained at 10−3 s−1 -10°C, is controlled by crack propagation, provided cracks exceed a critical size and are sharp. When short, or they long but blunted through creep deformation tip, nucleation new cracks.
