Abstract :The enhancement of snow modeling is attempted by taking into account the hardening phenomenon. The hardening model is developed based on the experimental results given by Shinojima. In this paper the long-term behavior of snow is extracted from the experiments, and it is found that the hardening can be induced due to snow deformation. Besides, the snow specimens possess distinct hardening properties in extensional and compressional deformations. The application of the hardening model to finite element analysis is achieved. The settlement force acting on a beam embedded in deep snow is analyzed. The numerical results show that the introduction of the deformation-hardening model can provide good agreement with experimental results.
