An Educational Software for Nonlinear Analysis of Truss Structures Using a Position‐Based FEM Formulation

open access: yesComputer Applications in Engineering Education, Volume 34, Issue 3, May 2026.
ABSTRACT This study introduces a novel educational software for the analysis of 2D truss structures using a position‐based Finite Element Method (FEM). The software, named Truss Positional Finite Element Method Program (TPFEM), employs a Half‐Edge data structure to efficiently manage the geometric and topological information of truss elements.

Geometry-dependent laser damage resistance of fused silica metastructures: a multiphysics simulation investigation

open access: yesOpen Physics
Their opto-thermo-mechanical response fundamentally constrains the reliability of dielectric metasurfaces under high-power laser irradiation. In this study, we systematically investigate the thermomechanical behavior of cylindrical fused silica ...

Maneuverable Multilegged Locomotion through Anisotropically Arranged Soft Backbones in a Single‐Actuator Modular Miniature Robot

open access: yesAdvanced Intelligent Systems, Volume 8, Issue 4, April 2026.
A modular eight‐legged robot exploits anisotropically oriented soft I‐beam backbones to transmit vibration from a single unbalanced‐mass actuator, producing frequency‐dependent multimodal gaits. A pseudo‐rigid‐body model enables high‐fidelity MuJoCo simulation, while Bayesian parameter identification and reinforcement learning yield robust control ...

On Saint-Venant’s principle in dynamic linear viscoelasticity [PDF]

open access: yesQuarterly of Applied Mathematics, 1997
The Saint-Venant's principle (for elastostatics and elastodynamics) was earlier established in the linearized theory of quasi-static deformations for isotropic viscoelastic materials. Here the author extends the above principle to anisotropic bodies by investigating the spatial decay of dynamic viscoelastic processes in an anisotropic viscoelastic body

Assimilation of SWOT Reach Water Surface Elevation Product Toward Enhanced Basin‐Scale Discharge Modeling

open access: yesEarth and Space Science, Volume 13, Issue 4, April 2026.
Abstract The high‐resolution measurements of surface water recorded by the recently launched Surface Water and Ocean Topography (SWOT) mission offers unprecedented opportunities toward accurate characterization of basin‐scale river discharge. This paper presents the first India‐centric study regarding the potential of assimilation of SWOT Water Surface

Efficient Data Assimilation Method for Optimizing Prediction of Flow Field and Sediment Transport in Open Channel

open access: yesRiver Research and Applications, Volume 42, Issue 3, Page 580-593, March 2026.
ABSTRACT Accurately predicting open‐channel flow under complex conditions remains a challenge. This study introduces a novel synergetic self‐adaptive data assimilation (DA) framework, using a proportional‐integral‐derivative (PID) controller to dynamically calibrate the bed roughness parameter k s in a shallow‐water equation model (via the momentum ...

Rethinking the Filling Process of Mega‐Dam Cascades

open access: yesWater Resources Research, Volume 62, Issue 3, March 2026.
Abstract The filling process of large hydropower reservoirs is an often‐overlooked process that can attract most of the attention and criticisms of a dam's lifetime. Understanding what drove past filling efforts and exploring trade‐off solutions is therefore critical for regions where hydropower development is flourishing.

Hybrid GNN and temporal encoder models for flood forecasting in the Vu Gia–Thu Bon River Basin

open access: yesRiver, Volume 5, Issue 1, Page 3-21, February 2026.
Abstract Flood forecasting in river networks requires models that can capture both spatial dependencies across river basins and the temporal dynamics of hydrological processes. This study proposes a hybrid approach combining Graph Neural Networks (GNNs) with temporal sequence models, such as Long Short‐Term Memory (LSTM) networks and Transformer ...
