A Peridynamic Framework for Modeling Progressive Failure in Porous Sandstone Indentation

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT A state‐based peridynamic model is proposed to simulate the failure mechanisms in porous rocks, using Bentheim sandstone as a specific example. Experimental observations reveal a transition from brittle to ductile failure under increasing triaxial compression. This behavior is attributed to pore compaction. The peridynamic model is enhanced to

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

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
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 ...

Configurational Energy as a Microstructural Descriptor of Failure Precursors in 2D Frictional Granular Materials

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 5, Page 2470-2485, 10 April 2026.
ABSTRACT Localized deformation in dense granular materials, often culminating in the formation of shear bands, is a key failure mechanism in geotechnical and material systems. However, predicting the onset of such localization remains a fundamental challenge due to the system's inherent inelasticity and microstructural complexity.

Interfaces in Large Area 2D Materials Integration: From Epitaxial Growth and Clean Transfer to Interface‐Dominated Performance

Advanced Materials Interfaces, Volume 13, Issue 6, 16 March 2026.
This Review proposes an interface‐centric framework for large‐area 2D materials integration, linking wafer‐scale single‐crystal epitaxy, clean transfer and deterministic stacking, and interface‐dominated structure–property–device correlations. We summarize how interfacial symmetry and energetics govern nucleation/coalescence and adhesion‐controlled ...

Peridynamics with a Cube‐Shaped Neighborhood

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 1, March 2026.
ABSTRACT This paper investigates the effects of cube‐shaped neighborhoods in peridynamic theory as an alternative to the traditional spherical neighborhoods. We examine how different neighborhood geometries influence the behavior of various peridynamic formulations, including bond‐based models, state‐based formulations, and correspondence methods.

Methodological Frameworks for Computational Electrocatalysis: From Theory to Practice

Small Methods, Volume 10, Issue 5, 9 March 2026.
Computational modeling is widely used to investigate electrocatalytic reactions, yet accurately describing electrochemical interfaces remains challenging. This review outlines theoretical and computational strategies, based on density functional theory, to model reaction thermodynamics, solvation effects, applied bias, and kinetics.

An efficient semi‐analytical approach for the free vibration behavior of DWCNTs on elastic foundations based on nonlocal elasticity theory

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 106, Issue 3, March 2026.
Abstract In this study, a comprehensive analytical framework is developed to investigate the free vibration behavior of double‐walled carbon nanotubes (DWCNTs) resting on an elastic foundation, based on Eringen's nonlocal elasticity theory. The DWCNTs are modeled as two coupled Euler–Bernoulli (EB) beams, explicitly incorporating intertube van der ...
