Application of Similitude Rules in Calibrating Microparameters of Particle Mechanics Models
Abstract Fast determination and calibration of microparameters in particle mechanics models, which can not be directly measured in the standard laboratory tests, is the key to successful simulation. Since the nature of physical similar material test is same as that of microparamter calibration procedure, similitude rules are used to tackle this issue in this paper. Two modeling schemes are designed based on the similitude rules, and the feasibility of the designed schemes is analyzed. The results show that those desired microparameters can be obtained according to the designed schemes when the initial fabric of a model is accurately similar to that of its prototype. Particle resolution (L/D) and particle size distribution (Rmax/Rmin) are the two main factors influencing the fabric similarity between a model and its prototype, and the fabric difference results in the relative errors. When L/D is small and Rmax/Rmin is large, it is difficult to build a model similar to its prototype based on the designed schemes.
