Fatigue Crack Modeling of Railheads Using a Nonlinear Cohesive Zone Model

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT Subsurface fatigue crack growth within railheads can be deleterious leading to catastrophic failures in rails. This study aims to model the fatigue crack growth originating at the subsurface level within railheads. Towards that end, a finite element modeling approach is utilized wherein complex crack growth is explicitly modeled using a ...

Self‐Expanding Cardiovascular Stents: Potentials and Challenges of Shape Memory Biomaterials

Journal of Biomedical Materials Research Part B: Applied Biomaterials, Volume 114, Issue 6, June 2026.
ABSTRACT Cardiovascular diseases affect a large portion of the global population and remain leading causes of morbidity and mortality. Endovascular stenting, a minimally invasive procedure, enables the insertion and deployment of stents to restore arterial patency without open surgery.

Pose‐Independent Soft Haptic Ring for Joint‐Centered Directional Guidance via Multichannel Shape Memory Alloy Actuators

Small Structures, Volume 7, Issue 5, May 2026.
The Pose‐Independent Haptic Ring (PIHR) delivers four‐directional, joint‐referenced haptic cues using a compact multichannel serpentine SMA array embedded in a soft elastomer. By mapping circumferential normal indentation to a metacarpophalangeal (MCP)‐centered spherical coordinate system, the PIHR preserves consistent spatial meaning under arbitrary ...

Shakedown analysis of red mudstone fill material with different water contents

Journal of Rock Mechanics and Geotechnical Engineering
Understanding the shakedown behavior of fill material is paramount to estimate the deformation stability of railway subgrade. Especially for red mudstone fill material (RMF), the noticeable overestimation of bearing capacity would be encountered if the ...

Peculiarities of calculating the cyclic strength of important threaded joints

Journal of Civil Engineering and Management, 2002
The calculation of the strength of important threaded joints is started by defining the minimum size of the cross-section of bolts (studs). Then the static and cyclic strength is tested.
