Fatigue &Fracture of Engineering Materials &Structures, EarlyView.ABSTRACT The degradation of metallic materials due to hydrogen embrittlement (HE) poses critical challenges for structural reliability. Phase‐field models offer an energy‐based approach that does not require predefined crack paths and automatically determines crack initiation, growth, and coalescence.

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 ...

Kernel reconstruction in a semilinear parabolic problem with integral overdetermination [PDF]
, 2014 A semilinear parabolic problem of second order with an unknown solely time-dependent convolution kernel is considered. The missing kernel is recovered from an additional integral measurement. The existence, uniqueness and regularity of a weak solution is

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 5, Page 2648-2669, 10 April 2026.ABSTRACT This study presents large deformation computational methods to simulate lateral vehicular impacts on steel piles in granular soil. Soil‐mounted longitudinal barrier systems rely on energy dissipation in both the piles and the surrounding soil to safely redirect errant vehicles, so dynamic pile‐soil interaction is important for design ...

Mesh and Model Adaptivity for Multiscale Elastoplastic Models With Prandtl‐Reuss Type Material Laws
International Journal for Numerical Methods in Engineering, Volume 127, Issue 6, 30 March 2026.ABSTRACT Homogenization methods simulate heterogeneous materials like composites effectively, but high computational demands can offset their benefits. This work balances accuracy and efficiency by assessing model and discretization errors of the finite element method (FEM) through an adaptive numerical scheme.

Multiband Switchable Microwave Absorbing Metamaterials Based on Reconfigurable Kirigami–Origami
Advanced Functional Materials, Volume 36, Issue 23, 19 March 2026.A reconfigurable metamaterial featuring tunable microwave‐absorbing and load‐bearing performance is proposed. Stretchable kirigami and bistable origami configurations are integrated as actuating components, and the synergistic deformation mechanisms are systematically analyzed.
