In order to solve the current difficulties of modeling for designing grain silo considering silo shear during discharge. A new numerical model based on Discrete Element Method (DEM) is proposed from the micro levels. A DEM model based on triaxial test results is to examine the grain shear during silo discharge. Micro parameters comprise of the contact, material and mechanical models. The relationships between macro and micro mechanical parameters are built. Based on the results, this study proposed new methods of analyzing silo discharge, which provides cost effective and simple techniques to determine suitable input parameters for models of discrete element method and finite element method. Finally, the parameters given from numerical and experimental results have shown efficiency and rationality of this modeling method.
Key words: Macro parameters, micro parameters, PFC3D, triaxial tests, , ,
