A Discrete Element Method–Based Energetic Approach to Model Two‐Dimensional Fatigue Crack Propagation

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, Volume 49, Issue 5, Page 1420-1436, 10 April 2025.
ABSTRACT In this work, a fatigue crack propagation model is proposed using the two‐dimensional discrete element method (DEM). The challenge lies in describing the small progressive fatigue crack growth within a single cycle, which is typically much smaller than the size of the smallest particles, making it difficult to continuously capture the loss of ...

Bias Correction of Satellite Precipitation Estimation Using Deep Neural Networks and Topographic Information Over the Western U.S.

open access: yesJournal of Geophysical Research: Atmospheres, Volume 130, Issue 4, 28 February 2025.
Abstract Satellite‐based precipitation products (SPPs) have gained popularity among researchers due to their utility in hydrologic studies. Several gridded satellite‐based precipitation products with global coverage, such as the Integrated Multi‐satellitE Retrievals for GPM (IMERG) and the Precipitation Estimation from Remotely Sensed Information using

Discrete-element modeling of strain localization in a dense and highly coordinated periodic granular assembly

open access: yesFracture and Structural Integrity, 2022
Strain localization is one of the key phenomena which has been extensively studied in geomaterials and for other kinds of materials including metals and polymers. This well-known phenomenon appears when structure/material is closed to failure.

The Study of Water Content on the Coal Loading Performance of Thin Coal Seam Shearer Drum by Discrete Element Method (DEM)

open access: yesEngineering Reports, Volume 7, Issue 1, January 2025.
Loading methods, helical angles, and rotation speed of drum have significant effects on the loading rate of drum. In this study, Discrete Element Method (DEM) is used to study what effects of these several factors have on the loading rate under different water contents.

Macro–Microscopic Mechanical Study of Clay–Structure Interface Shear Behavior Using Direct Shear Testing and DEM Simulation

open access: yesAdvances in Civil Engineering, Volume 2025, Issue 1, 2025.
Understanding the interface shear behavior between clay and structures is crucial in geotechnical engineering. The mechanism of the roughness effect in the shear process between the clay and structures was studied to reveal the macroscopic and microscopic interface shear behavior.
