Vision Transformers for Modeling of Nonlinear Heterogeneous Materials

International Journal for Numerical Methods in Engineering, Volume 127, Issue 14, 30 July 2026.
ABSTRACT Multiscale simulations of nonlinear heterogeneous materials and composites are challenging due to the prohibitive computational costs of high‐fidelity simulations. Recently, machine learning (ML) based approaches have emerged as promising alternatives to traditional multiscale methods.

Neural‐Initialized Newton: Accelerating Nonlinear Finite Elements via Operator Learning

International Journal for Numerical Methods in Engineering, Volume 127, Issue 14, 30 July 2026.
ABSTRACT We propose a Newton‐based scheme, initialized by neural operator predictions, to accelerate the parametric solution of nonlinear problems in computational solid mechanics. First, a physics‐informed neural operator based on conditional neural fields or Fourier neural operators is trained to approximate the nonlinear parametric solution of the ...

A Quasicontinuum Method With Optimized Local Maximum‐Entropy Interpolation and Heaviside Enrichment for Heterogeneous Lattices

International Journal for Numerical Methods in Engineering, Volume 127, Issue 14, 30 July 2026.
ABSTRACTLattice systems are indispensable for modeling and analyzing physical phenomena in materials with discrete or heterogeneous micro‐ or meso‐structures. However, the computational requirements for practical engineering applications of lattice systems remain high.

The Vegetated‐Canopy Roughness Sublayer Through a TKE‐Budget Lens

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 13, 16 July 2026.
Abstract It is well understood that vegetated canopies perturb the atmospheric flow within and immediately above the canopy, deviating from the inertial sublayer (ISL) regime characteristic of non‐vegetated rough surfaces. Only above a certain height, denoted as the roughness sublayer height (RSL, z∗ ${z}_{\ast }$), do these flows return to ISL‐like ...

A Hybrid‐High Order Method for Fracture Modelling

International Journal for Numerical Methods in Engineering, Volume 127, Issue 13, 15 July 2026.
ABSTRACT In this work we introduce a new Hybrid High‐Order method for the numerical simulation of fracture propagation based on phase‐field models. The proposed method: supports general meshes made of polygonal/polyhedral elements, which provides great flexibility in mesh design and adaptation; can accommodate large variations of both the displacement ...

Generalised Phase Field Modelling of Fracture in Gyroid Structures: Numerical and Experimental Insights Using Additively Manufactured Polylactic Acid (PLA) Specimens

International Journal for Numerical Methods in Engineering, Volume 127, Issue 13, 15 July 2026.
ABSTRACT This study presents a three‐dimensional cohesive phase field framework for simulating quasi‐static fracture in Gyroid lattice structures. To the authors' knowledge, this is one of the first experimentally validated applications of a diffuse cohesive phase field model to describe damage and fracture evolution in additively manufactured ...

Cross‐Scale Synergistic Optimization for Miniature Meta‐Liquid Hybrid Zoom Imaging

Nanophotonics, Volume 15, Issue 13, 13 July 2026.
A physically constrained optimization framework links electrowetting liquid lenses and metasurface dispersion engineering to realize a compact visible‐band achromatic zoom imager. By co‐optimizing zoom actuation, meta‐atom manufacturability, and system aberrations, the design achieves 1.5x zoom in a 15.5 mm track and clarifies robustness against ...
