Design and Development of an Accessible Clip Gauge Extensometer for CMOD Measurement in Fracture Mechanics

Engineering Reports, Volume 8, Issue 2, February 2026.
A low‐cost clip gauge extensometer for crack mouth opening displacement was developed from accessible procedures and materials. Accuracy and repeatability comparable to commercial devices were demonstrated in calibration and fracture tests, enabling reliable measurement in CT specimens for resource‐constrained laboratories.

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.

Validation and Investigation of a Multiaxial Progressive Damage Model Through Glass Fiber Reinforced Tube Specimen Under Fatigue Loading

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 1, Page 84-101, January 2026.
ABSTRACT In the field of composite structure fatigue simulations, progressive damage models are common tools. However, these models are dependent on the definition of meta parameters, such as the residual stiffness following an interfiber failure mode. This study presents a progressive damage model utilizing shell elements, with the material parameters

Tunneling Defect Analysis in 6‐mm aluminum Plates Using FSW Butt Joints: An Experimental and Numerical Study

Advances in Materials Science and Engineering, Volume 2026, Issue 1, 2026.
The formation of tunnel defects and their prediction have received far less attention than flow behavior in friction stir welding (FSW) operations, even though the former has been the subject of substantial study. Rotational velocity, plasticized area, and defect generation were the variables examined in this research.

Stimulated Volume Determination of a Horizontal Well in a Shale Oil Reservoir in the Vaca Muerta Formation and Its Interaction With Existing Fracture Networks

Advances in Materials Science and Engineering, Volume 2026, Issue 1, 2026.
Hydraulic fracturing is a stimulation technique that plays a critical role to provide transport path networks in unconventional shale reservoirs, yet the quantitative characterization of fracture propagation, its interaction with natural discontinuities, and the resulting stimulated volume remain challenging in heterogeneous formations such as the Vaca
