شبیه سازی عملیات تخلیه سیلو و باکت با روش المان گسسته (مقاله 16 ص انگلیسی)

The discrete element method (DEM) is a promising approach to model machine–granular material interaction. The accuracy of DEM models depends on the model parameters. In this study a calibration process is developed to determine the parameter values. Laboratory shear tests and compressions tests are used to determine the material internal friction angle and stiffness, respectively. These tests are repeated numerically usingDEMmodels with different sets of particle friction coefficients and ...
