The behaviour of a granular flow a t a boundary cannot be specified independently of what is happening in the rest of the flow field. This paper describes a study of two fictitious, but instructive, flat boundary types using a computer simulation of a twodimensional granular flow with the goal of trying to understand the possible effects of the boundary on the flow. The two boundary conditions,...

statement of problem: currently there are three recognized theories about the diameter of prepared dowel space in endodontically treated teeth. diameter of the dowel is commonly contributed to the root fracture. purpose: this study used a 3 dimensional (3d) finite element method to predict stress distribution in endodontically treated central maxillary tooth with cast post and core with various...

Introduction: We have modified the open-source program SatStress (http://code.google.com/p/satstress), developed at the University of Colorado-Boulder and JPL [1], used for calculating the tidal stresses on a satellite that is fully differentiated into a rocky core, a global subsurface ocean, and a decoupled, ice shell. Wahr et al. (2009) [1] used gravitational potential theory to determine the...
