Finite Element Modeling of a Thermoplastic Polyurethane Ball for Rolling Seismic Isolation
Earthquake Engineering &Structural Dynamics, Volume 55, Issue 4, Page 926-946, 10 April 2026.ABSTRACT The Elastomeric‐Ball Pendulum (EBP) system, which consists of an elastomeric ball rolling on a spherical concrete surface, has been proposed as an isolation system for lightweight structures. Experimental tests have shown that the mechanics of such a rolling ball are remarkably complicated because the vertical load changes the shape of the ...

Seismic Design of Concrete Dams: An Integrated Risk‐Informed Performance‐Based (RIPB) Framework
Earthquake Engineering &Structural Dynamics, Volume 55, Issue 5, Page 1019-1049, 25 April 2026.ABSTRACT This paper advances the integration of risk‐informed principles into the seismic design of dams—a domain long guided by standards‐based, largely deterministic approaches. While performance‐based earthquake engineering is well established for buildings and bridges, its systematic adoption in dam engineering remains limited. We first address two

steel research international, Volume 97, Issue 4, Page 2241-2249, April 2026.Cold spray deposition of stainless steel (grade: SS304) is evaluated for marine applications, with emphasis on martensitic transformation during impact. Analytical modeling, simulations, and experiments reveal that helium‐assisted spraying of fine powders promotes cooling below the martensitic start temperature, enabling up to ≈40% austenite to ...

Fault Friction, Plate Rheology, and Mantle Torques From a Global Dynamic Model of Neotectonics
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.Abstract Improvements in software, parallel computing, global data sets, and laboratory flow‐laws help to develop the global Earth5 thin‐shell finite‐element model of Bird et al. (2008, https://doi.org/10.1029/2007jb005460) into a benchmark study. All experiments confirm that modeled faults (other than megathrusts) have low effective friction of 0.085 ±

The Mean Across‐Shore Coastal Upwelling Cell in the Southern California Current System
Journal of Geophysical Research: Oceans, Volume 131, Issue 4, April 2026.Abstract Equatorward winds off California transport coastal surface waters offshore, which are replaced by deeper onshore flow that upwells. The mean upwelling cell is rarely measured directly because its magnitude is small compared to other variability.

Interior Models of Mercury and Conditions for Iron Snow Formation in a Fe‐S‐Si Core
Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.Abstract Mercury's unique interior structure and magnetic field generation remain to be fully understood. We construct models to further constrain Mercury's interior and test the hypothesis that iron snow within the liquid core drives the dynamo.
