The discrete element method (DEM) is used to model granular materials and analyse a wide
range of related applications. However, accurate predictions can only be made if the input …

Sand production in oil and gas wells can occur if fluid flow exceeds a certain threshold
governed by factors such as consistency of the reservoir rock, stress state and the type of …

Microbially induced calcium carbonate precipitation (MICP) has attracted much attention as
a promising green technique for soil improvement. Despite the significance of precipitation …

This paper deals with the formulation, calibration, and validation of the Lattice Discrete
Particle Model (LDPM) suitable for the simulation of the failure behavior of concrete. LDPM …

This report explores the effects of particle shape and content of fines on the shear behavior
of sand-fines mixtures using a two-dimensional discrete element method. The contributions …

This paper presents a new three-dimensional (3D) contact model incorporating rolling and
twisting resistances at inter-particle contact, which can be introduced into the discrete …

Soil-rock mixture (SRM) that is seriously affected by multiple factors such as particle
morphology, grading, and composition has been widely used in geotechnical engineering …

The Lattice Discrete Particle Model (LDPM) formulated in the preceding Part I of this study is
calibrated and validated in the present Part II. Calibration and validation is performed by …

This paper presents numerical modelling of rock cutting processes. The model consists of a
tool–rock system. The rock is modelled using the discrete element method, which is suitable …

A series of monotonic and cyclic triaxial shearing tests on Toyoura sand are simulated by
discrete element method (DEM) incorporating rolling resistance. The input parameters are …
