The temperature and strain rate-dependent compressive behaviour of ice-1h was investigated through molecular dynamics simulations. The ice strength increased in response to a decrease in the initial temperature and an increase in the strain rate. Various deformation mechanisms depended on the ice's initial temperature. Solid-liquid phase transformation was more likely to at a relatively high temperature. However, solid-solid phase transformation and dislocation-like glide were observed at relatively low temperatures. Experimental observations on the strength versus strain rate relationship of ice could be interpreted based on a prior study by Wu and Prakash 1.
