This paper presents discrete element method (DEM) simulations with experimental
comparisons at multiple length scales—underscoring the crucial role of particle shape. The …

A micro–macro elastoplastic micropolar continuum model for granular materials in the dry
and pendular states is proposed on the basis of thermodynamics. The independent …

In this paper we study the phenomenon of localization of deformation in fault gouges during
seismic slip. This process is of key importance to understand frictional heating and energy …

The application of the Physics-Informed Neural Networks (PINNs) to forward and inverse
analysis of pile–soil interaction problems is presented. The main challenge encountered in …

A smoothed particle hydrodynamics code based on micropolar continua for geomaterials is
developed for problems involving large deformation and shear strain localization. Two …

Understanding the stress regime that develops in the vicinity of reinforcements in reinforced
soil masses may prove crucial to understanding, quantifying, and modeling the behavior of a …

A constitutive model for simulation of the behavior of unsaturated interfaces is presented
here. The model is an extension of an existing critical state compatible interface model for …

Although commonly ignored in conventional design, cost savings could be possible if a
proper assessment of the effect of matric suction in retaining structures with unsaturated …

The purpose of this work is to study the mechanical behavior of microstructured materials, in
particular porous media. We consider a detailed description of the material through a …

The moving particle semi-implicit method is further extended to study the effect of replacing
the empirical start-up friction coefficient with shear strength parameters of dense granular …
