Fracture Assessment of DEMO Divertor Components Under Thermo‐Mechanical Loads

Macromolecular Symposia, Volume 415, Issue 3, June 2026.
ABSTRACT Nuclear fusion represents a promising pathway toward large‐scale, sustainable, and low‐impact energy production. However, the extreme operating conditions within fusion reactors, characterized by high temperatures, intense neutron irradiation, and severe mechanical and magnetic loads, place significant demands on the structural integrity of ...

Seasonal Ice Dynamics Control the Timing of Crevasse Drainage at a Fast‐Flowing Outlet Glacier

AGU Advances, Volume 7, Issue 3, June 2026.
Abstract Crevasse field drainage transfers at least half of the seasonal runoff from the surface to the bed of the Greenland Ice Sheet, but the patterns of drainage are complex and spatio‐temporally heterogenous. To better understand controls on crevasse drainage processes, we use an automated deep learning method to map the seasonal filling and ...

Multi‐Scale Rate‐ and Roughness‐Dependent Frictional Constitutive Law and Dynamic Earthquake Sequence Simulation

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract The physical mechanisms that govern the multi‐scale source properties of earthquakes, such as fracture energy scaling, where the dynamic energy dissipation of earthquakes scales with fault slip, remain debatable. We introduced the rate‐ and roughness‐dependent friction (RRF) law which accounts for the multi‐scale roughness evolution of the ...

Iceberg calving of Thwaites Glacier, West Antarctica: full-Stokes modeling combined with linear elastic fracture mechanics [PDF]

The Cryosphere, 2017
Thwaites Glacier (TG), West Antarctica, has been losing mass and retreating rapidly in the past few decades. Here, we present a study of its calving dynamics combining a two-dimensional flow-band full-Stokes (FS) model of its viscous flow with linear ...

Influence of Surface Flaw Interaction on Failure Assessment Diagram in the Framework of Fitness‐for‐Service Procedures

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 5, Page 1877-1894, May 2026.
ABSTRACT This study investigates the influence of closely spaced surface‐flaw interaction on failure assessment diagrams (FADs) used in fitness‐for‐service evaluations, addressing the conservatism introduced when standards such as BS 7910 and API 579 recharacterize interacting flaws as a single bounding crack.
