The application of mesh-free discrete element method (DEM) for modeling macroporous inverse opals is proposed. developed and implemented DEM-based strategy applied to analyze stiffness strength made pure silica coated with titania layers various thicknesses. Also, the influence porosity initial packing on properties material investigated. Simulation results have shown that due heterogeneous mac...

The present paper deals with a micromechanical model of interface able to couple the damage (micro-crack) evolution, the non-penetration conditions (Signorini equations) and the friction effect (Coulomb’s law). At a typical point of the interface, a Representative Volume Element (RVE) is considered; it is characterized by the presence of two different materials and by a microcrack evolving alon...

In this paper, we derive the second-order crack opening displacement tensor for an arbitrarily oriented elliptical in elliptically orthotropic (EO) matrix. This result is obtained explicit closed form. The approach based on Saint-Venant’s idea of linear transformation between boundary value problems and isotropic bodies. solution utilizes classical representation ellipsoid where smallest aspect...
