The Effect of Elastic–Plastic Mismatch and Interface Proximity on the Fracture Toughness of Ti‐TiN Thin Films

open access: yesAdvanced Engineering Materials, Volume 27, Issue 15, August 2025.
Multilayering of TiN film with metallic Ti film is adopted to enhance the fracture resistance of TiN thin films. Plastic dissipation within Ti with process zone size of ≈250 nm, along with elastic–plastic mismatch driven changes to crack driving force enhances the crack growth resistance by ten times, enabling physics informed design of optimized ...

Experimental Simulation Investigation on Mechanism and Criterion of Impact‐Induced Rockburst in Gaoloushan Deep Tunnel

open access: yesEnergy Science &Engineering, Volume 13, Issue 8, Page 4252-4266, August 2025.
ABSTRACT During the excavation of a deep‐buried tunnel by the drilling and blasting method, the dynamic stress of blasting may cause the disorderly release of high energy in the rock mass during the blasting process of deep high‐energy rock. Blasting vibration is one of the main factors inducing dynamic disasters (such as rockbursts) in the surrounding

Closed‐Form Hypoplastic Solutions for Normally Consolidated Soil in Element Tests

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, Volume 49, Issue 11, Page 2492-2505, 10 August 2025.
ABSTRACT The hypoplastic theory has gained significant attraction in the geomechanics community for constitutive modeling and numerical simulation. However, the absence of an analytical benchmark for numerical simulations incorporating the hypoplastic model remains a notable gap. This study revisits the basic hypoplastic model for normally consolidated

A DEM Model for Assessing the Mechanical Effects of CO2 Alteration in a Carbonate Rock

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, Volume 49, Issue 11, Page 2559-2573, 10 August 2025.
ABSTRACT CO2 injection in the subsurface is considered an option to improve oil and gas production and, more recently, to store CO2. Consequently, there is a need to better understand the interactions between CO2 and rock deposits. Among the primary deposit candidates are carbonate rocks.
