Experimental Study on Stress Wave Propagation Crossing the Jointed Specimen with Different JRCs

Shock and Vibration, 2021
Most of the rock masses in the outer crust of the Earth are discontinuous. They are divided by joints, faults, fractures, etc. And those discontinuities, generally referred to as joints, greatly affect the property of the rock masses.

Modeling the Spatial Interplay Between Migration and Environmental Conditions

Environmetrics, Volume 37, Issue 1, January 2026.
ABSTRACT The measurement and modeling of migration patterns and potential drivers are often limited by the quality of spatial data at local levels. Our aim is to address these constraints by advantaging of consolidated techniques in geospatial regression and emerging machine‐learning approaches to explore how selected contextual socio‐economic and ...

Quantifying the morphology of rock joints and updating the JRC–JCS criterion considering the asperity distribution

Geomechanics and Geophysics for Geo-Energy and Geo-Resources
Roughness ubiquitously prevails in rock joints and controls the shear behaviours, permeability and damage characteristics of rock joints. A plethora of investigations have focused on the description of joint roughness; however, a detailed method for ...

A Probabilistic Cut Finite Element Method With Random Field Generator and Bayesian Model Calibration for Flow Through Rough Cracks

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 1, Page 298-320, January 2026.
ABSTRACT A new model for the simulation of fluid flow through rough cracks is presented. The model combines a probabilistic cut finite element method (PCutFEM) to capture the unfitted boundary condition at the fluid interface, with a stochastic random field generator to represent the crack asperities.

Using rodogram function to characterize hurst coefficient in rock profiles

REM: International Engineering Journal
Roughness is a fundamental feature to define rock deformability and resistance. A detailed characterization of discontinuity surface geometry is essential for understanding some of the rock’s mechanical behaviors.

On the Classification of Vehicle Cut‐In Scenarios Severity: Empirical Evidence to Validate the Severity Classification of UN R157

IET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.
This study validates the Fuzzy Safety Model (FSM) as a tool for classifying the difficulty of vehicle cut‐in scenarios, supporting its role in Automated Lane Keeping Systems (ALKS) safety assessments. Results from a test campaign demonstrate the FSM's effectiveness in categorising preventable cases and its broader applicability in enhancing automated ...

Shear Behavior and Shear‐Flow Coupling Mechanisms of Red‐Clay‐Infilled Joints Under High Water Pressure

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
Rock joints are considered as a discontinuity between two continuous media. The presence of infilled joints influences the mechanical and hydraulic properties of joint rock. Understanding these properties is critical for assessing underground excavation safety, slope stability, and water inrush risk.
