内容記述 | The mechanical property of one ice sample (No. 143) taken from the 100m depth at Mizuho Station was investigated with the stress-strain tests in uniaxial compression at temperatures of -6°and -16℃. Strain rate employed in experiments ranged from (10)^<-7> to (10)^<-6>s^<-1>. Stress-strain curves obtained are classified into two types : stress-yield type and stress-saturation type, according to the occurrence and non-occurrence of yield drop due to the internal cracking. The relationships between the maximum stress obtained from the curves and the strain rate (the stress dependence of the strain rate) thus obtained were compared with those for core samples taken at Byrd Station. It was found that Mizuho core sample resembled Byrd core sample No. 145 (300m depth) in the mechanical property shown in the relationships stated above Peculiarity in the property exhibited at -16℃ experiments is interpreted by the generation of cracks during deformation of high strain rate. | |||||
