Abstract

We have developed a model for friction in a dry granular material,that allows multiple reversible transitions between stick and slipcontacts. The ultimate purpose of the model is to simulatedeposition processes. During these processes a pile structure isformed that is repeatedly destabilised by addition of new material.The present model does not yet include rotation. The model is testedfor a few simple systems. Finally we perform more extensive granulardynamics simulations using the model for 2D and 3D systems. In eachsystem, a steady flow of material is dropped onto a rough surface.DOI : http://dx.doi.org/10.22342/jims.13.2.83.173-189

Abstract

In this paper, it is proved that the supremum of a family of fuzzy number scan be finitely approximated via Lp metrics and the concrete approaches are given. As a byproduct, it is proved that the L1 metric d1 defined via cut-set is equivalent to ametric which can be calculated directly via membership functions. Since the Lp metrics are analytic in nature, the results in this paper may have interesting applications infuzzy analysis. For example, it may provide a method for the computation of various fuzzy-number-valued integrals.DOI : http://dx.doi.org/10.22342/jims.13.2.88.197-208
