Experimental Technique for Ice under Dynamic Compressive Loading
Abstract:
Experiments on the dynamic behavior of ice in compression were carried out by means of SHPB apparatus. The specimens were to-10°C~-25°C and the tested strain rate ranged from 700/s to 1000/s. Strain-rate effects and the influence of freezing preserve time were studied. It was observed that the dynamic compressive strength of ice has an effect of strain-rate enhancement and the freezing preserve time has no influence to its dynamic compressive strength. In addition, a Pulse shaping technique to avoid the specimen failing before stress uniformity in ice specimen was presented.
