Space‐Time Boundary Elements on Graded Meshes for 3D Elastodynamics
International Journal for Numerical Methods in Engineering, Volume 126, Issue 20, 30 October 2025.ABSTRACT The solution to the elastodynamic equations in the exterior of a polygonal or polyhedral domain or a screen exhibits singularities at corners and edges. This paper presents a space‐time boundary element method in 3D on algebraically graded meshes to resolve these singularities, based on recently obtained error estimates for the weakly singular

Differentiating Frictionally Locked Asperities From Kinematically Coupled Zones
Journal of Geophysical Research: Solid Earth, Volume 130, Issue 10, October 2025.Abstract Seismogenic areas on plate‐boundary faults resist slipping until earthquakes begin. The delay in slip relative to plate motion, termed slip deficit, represents plate coupling as an interseismic proxy of seismic potential. However, when a part of a frictional interface sticks together (locked), the unlocked sliding surroundings are braked and ...

RAB5A Promotes Active Fluid Wetting by Reprogramming Breast Cancer Spheroid Mechanics
Advanced Science, Volume 12, Issue 34, September 11, 2025.RAB5A‐mediated unjamming enhances active wetting through distinct biomechanical processes: a) upregulation of specific integrin subunits, enhanced focal adhesions kinetics and activity; b) supracellular organization relying on nanoscale integrin clustering, and the formation of a stiff and collective actin cable; and c) softening of the spheroid core ...

Proceedings in Applied Mathematics and Mechanics, Volume 25, Issue 3, September 2025.ABSTRACT The sandwich principle was applied to a basic mechanics lecture using smartphone experiments with alternating individual and collective learning phases. One experiment covered static friction and one the acceleration of cylinders. With the aim for a more learner‐centered lecture, the individual learning phases started with an application of ...

Concurrent Optimization of Structures and Anisotropic Materials for Mechanical Cloaking
International Journal for Numerical Methods in Engineering, Volume 126, Issue 6, 30 March 2025.ABSTRACT This paper studies the concurrent optimization of structural topologies and material properties for mechanical cloaking problems, in which the macrostructures, microstructures, and novel spatially‐varying microstructure orientations of the cloaking devices are simultaneously considered and form a multiscale topology optimization problem.

Riemannian Shape Optimization of Thin Shells Using Isogeometric Analysis
Proceedings in Applied Mathematics and Mechanics, Volume 25, Issue 1, March 2025.ABSTRACT In this contribution, we consider the optimal shape design of thin elastic shell structures based on a linearized shell model of Koiter's type, whose shape can be described by a surface immersed in three‐dimensional Euclidean space. We regard the set of unparametrized immersions of the surface as an infinite‐dimensional Riemannian shape space ...

Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 7, Page 841-858, 10 March 2025.Abstract Accurately predicting the dynamics of complex systems governed by partial differential equations (PDEs) is crucial in various applications. Traditional numerical methods such as finite element methods (FEMs) offer precision but are resource‐intensive, particularly at high mesh resolutions.

On the Use of Block Low Rank Preconditioners for Primal Domain Decomposition Methods
International Journal for Numerical Methods in Engineering, Volume 126, Issue 3, 15 February 2025.ABSTRACT This article investigates the use of the block low rank (BLR) factorization, recently proposed in the MUMPS solver, to define efficient and cheap preconditioners for primal domain decomposition methods, such as the Balancing Domain Decomposition method (BDD) and its adaptive multipreconditioned variant.
