Abstract (may include machine translation)
A stochastic model that describes the jamming and reorganization of grains associated with dragging an object through a granular medium is introduced. The model reproduces the sawtooth pattern of temporal evolution of the drag force and the 1/f2 high frequency tail of the power spectrum, and predicts the period of the sawtooth pattern and a power-law avalanche size distribution.
