An Anisotropic Constitutive Model for Crushable Geomaterials Based on Non‐Stationary Critical State Line Concept

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 16, Page 5919-5935, November 2026.
ABSTRACT In this paper, the dependencies of granular soil behaviour on particle crushing and fabric anisotropy are formulated within a novel model based on bounding surface plasticity theory enriched by the non‐stationary critical state line (NCSL) concept.

Comparison of Mesoscale Crack Advance and Process Zone Element Approaches for Simulating Ductile Crack Trajectories in Steel

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 11, Page 4850-4862, November 2026.
ABSTRACT Rigorous application of continuum damage mechanics (CDM) models coupled with crack propagation schemes can predict crack branching or zigzag trajectories near the crack tip, even when the macroscopic crack growth is straight. This arises from oscillations in the local damage field and is consistent with experimental observations of ductile ...

Device‐Measured 24‐h Movement Behaviors and Arterial Intima‐Media Thickness in Young Adults

Scandinavian Journal of Medicine &Science in Sports, Volume 36, Issue 11, November 2026.
ABSTRACT Physical activity, including light physical activity (LPA) and moderate‐to‐vigorous physical activity (MVPA), sedentary behavior (SED), and sleep, often referred to as “24‐h movement behaviors”, are modifiable behaviors that may be associated with arterial intima‐media thickness (IMT).

Corrigendum to: Large-scale true-triaxial rock testing apparatus [PDF]

EPJ Web of Conferences
The authors have inadvertently omitted to include Martin Feinendegen in the list of authors, despite his close involvement with this work. This occurred because the authors forgot to update the provisional list of authors mentioned in their abstract when
