Anisotropic Biot Coefficient of Fractured Rocks Drives Failure Conditions in Pressurized Reservoirs

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract We present a theoretical framework to quantify the equivalent Biot coefficient tensor of fractured rock masses based on the properties of both the intact porous matrix and the fracture network. Our results show that the presence of dominant fracture sets produces an anisotropic equivalent Biot tensor, with larger values in the direction ...

Seta‐Inspired Mechano‐Intelligent Janus Bandage with Coordinated Adhesion–Contraction for Minimizing Scarring

Advanced Materials, Volume 38, Issue 34, 17 June 2026.
We developed a bioinspired mechano‐intelligent Janus bandage (MIB) with a hydrophobic flat exterior and a hydrophilic interior featuring gecko‐mimicking wedged microstructures, fabricated via micromolding and anisotropic plasma treatment. The MIB dynamically synchronizes adhesion and contraction, enabling precise force modulation.

A Novel Decomposition‐Based Growth Model for Simulating Stress‐Modulated Spinal Growth

International Journal for Numerical Methods in Biomedical Engineering, Volume 42, Issue 6, June 2026.
This study introduces the first decomposition‐based finite‐strain growth model for a simplified Functional Spinal Unit, where growth occurs simultaneously with mechanical loading. The approach eliminates the major physical inconsistency of sequential methods—growth in an artificial stress‐free configuration—while preventing mesh distortion and ...

Cyclic behavior of reinforced sand under principal stress rotation

Journal of Rock Mechanics and Geotechnical Engineering, 2017
Although the cyclic rotation of the principal stress direction is important, its effect on the deformation behavior and dynamic properties of the reinforced soil has not been reported to date.

Patient‐Specific In Silico Prediction of Outcomes of Partial Continuous‐Flow LVAD Treatment in Peripartum Cardiomyopathy

International Journal for Numerical Methods in Biomedical Engineering, Volume 42, Issue 6, June 2026.
Partial continuous‐flow left ventricular assist device (LVAD) treatment of peripartum cardiomyopathy provides greater functional improvement for higher than lower disease severity. The left ventricle and LVAD jointly generate ventricular output for mild functional impairment, where the left ventricular contribution decreases with increasing LVAD ...

Capturing Complex Rate‐Dependent Behaviors of Saturated Clays: A Fractional Consistency Kinematic Hardening Viscoplastic Approach

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 8, Page 3281-3296, 10 June 2026.
ABSTRACT Saturated high plasticity clays show complex nonlinear, rate‐dependent, and hysteresis behaviors under non‐monotonic stress paths, requiring advanced mathematical constitutive equations for accurate description. Taking into account the inherent advantages of kinematic hardening mechanisms in simulating complex stress histories, this paper ...
