摘要

Based on Perzyna's elasto-viscoplastic theory and Drucker-Prager yield function, an elasto-viscoplastic constitutive model is presented to study the behavior of frozen soil under impact loadings. Based on the experimental investigations at different strain rates and different temperatures by means of split Hopkinson pressure bar (SHPB), the Drucker-Prager yield function has been modified by adopting the effect of strain rate. A dynamic constitutive model for frozen soil is proposed and all the parameters of the model are determined. A good agreement is achieved between the theoretical predictions and the experimental results, which indicates that the model and the yield function are reasonable.
