Equivalence Between the Co‐Rotational Finite Element Method and the Absolute Coordinate Formulation in Multibody Dynamics

International Journal for Numerical Methods in Engineering, Volume 127, Issue 2, 30 January 2026.
ABSTRACT Geometric nonlinearity arises in problems involving large displacements and rotations, where traditional linear assumptions fail. In the finite element community, several formulations have been developed to address these complexities; the corotational finite element formulation (CRF) has proven to be an efficient alternative to generic total ...

FENet: A Physics‐Informed Dynamics Prediction Model of Pantograph‐Catenary Systems in Electric Railway

IET Intelligent Transport Systems, Volume 19, Issue 1, January/December 2025.
In this manuscript, we proposed physics‐informed surrogate model, called FENet, for the first time to solve the interaction of pantograph‐catenary system. In recent years, much progress has been achieved in PCS modelling solutions. Existing solutions, however, suffer from two significant limitations: 1) An urgent concern arises regarding the ...

Dynamics of Variable Stator Vane Adjustment Mechanism Considering the Flexibility of Linkage

International Journal of Aerospace Engineering, Volume 2025, Issue 1, 2025.
The variable stator vane adjustment mechanism plays a vital role in preventing the occurrence of surge due to its complex multistage linkage mechanism. Initially, the flexible body is modeled using the absolute nodal coordinate formulation method, followed by the formulation of rigid–flexible coupled dynamics equations using the Lagrange equations of ...

Steady Flow Over a Finite Patch of Submerged Flexible Vegetation

Water Resources Research, Volume 60, Issue 1, January 2024.
Abstract An immersed boundary‐finite element with soft‐body dynamics has been implemented to study steady flow over a finite patch of submerged flexible aquatic vegetation. The flow structure interaction model can resolve the flow interactions with flexible vegetation, and hence the reconfiguration of vegetation blades to ambient flow.

Dynamic Modeling and Active Vibration Control of Piezoelectric Laminated Structure Based on Macrofiber Composite

Structural Control and Health Monitoring, Volume 2024, Issue 1, 2024.
In this paper, a ground‐based experimental system for solar array active vibration suppression has been established. Firstly, in order to establish an accurate model of the solar array, the solar array is regarded as a flexible cantilevered thin plate, and the corresponding dynamical equations are derived using the absolute nodal coordinate method.
