We have attempted a multiscale and quantified characterization method of the contact in three-dimensional granular material made of spherical particles, particularly in cemented granular material. Particle contact is defined as a type of surface contact with voids in its surroundings, rather than a point contact. Macro contact is a particle contact set satisfying the restrictive condition of a ...

This study was conducted to determine the macro and micro element contents of fourteen peanuts in Turkey. Virginia (NC-7, Halisbey, Arıoğlu-2003, Sultan Flower-22, Osmaniye-2005, Brantley, Wilson, Batem-5025, Batem-Cihangir, NC V 11 Polen) Runner (Georgia Green) Spanish (Florispan) market types have been evaluated. The research for two years (2015 2016) under main crop conditions trial areas be...

Abstract The paper presents the crashworthiness optimization of a thin-walled frame applied as energy-absorbing element in car structure. Crushing parameters S-frame are modeled using macro-element methodology. This method is implemented Visual Crash Studio software that enables very fast simulation structural behavior during impact. objective to determine optimal dimensions cross-section achie...

This paper presents numerical investigations using the mesoscale approach coupled with discrete macro-element for masonry structures , i.e., each represents a single unit stone. At first, parametric analyses are performed on U-shape prototype made Nonlinear static to investigate parameters that affect results when pattern representation is adopted. Results demonstrate how powerful alternative m...
