This paper investigates the influence of intergranular friction and grain size distributions on initial void ratio a granular sample subjected to isotropic compression loading. In field geomechanics, besides loading path evolution microscopic properties, is crucial key factor that governs mechanical behavior geomaterials. By using Discrete Element Model (DEM) performed an idealized 2D assembly ...

This paper follows up on a reference that inspired MDPI’s topic “Stochastic Geomechanics: From Experimentation to Forward Modeling”, in which the authors populated spatio–temporal database of boundary displacement fields from series triaxial sand specimens using three-dimensional (3D) digital image correlation analysis. The was curated and is currently available scientific community for further...

This research includes of the numerical modeling of fluids in two-dimensional cavity. The cavity flow is an important theoretical problem. In this research, modeling was carried out based on an alternating direction implicit via Vorticity-Stream function formulation. It evaluates different Reynolds numbers and grid sizes. Therefore, for the flow field analysis and prove of the ability of the sc...

Deformation and strength behavior of geomaterials in the preand post-failure regimes are of significant interest in various geomechanics applications. To address the need for development of a realistic constitutive framework, which allows for an accurate simulation of pre-failure response as well as an objective and meaningful post-failure response, a strain gradient plasticity model is formula...

Background: One of the current problems in studying the mechanical properties and behavior of structurally inhomogeneous media with cracks is the characterization of acoustic wave propagation. This is especially important in Geomechanics and prognosis of earthquakes. Methods: In this work, the authors propose an approach that could simplify characterization of wave propagation in medium with cr...
