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 ...

Piezoelectric Sensing of Rigid‐Flexible Coupled Free‐Edge Rectangular Plates

International Journal of Aerospace Engineering, Volume 2026, Issue 1, 2026.
With the rapid development of space technology, rigid‐flexible coupling systems are widely used in aerospace structures. Attitude‐vibration coupling control requires a deep understanding of the rigid‐flexible coupling dynamics of these systems. In the presented work, a center rigid body coupled with a rectangular thin plate was studied.

Improved Performance and Stability of Perovskite Solar Cells by Incorporating Silicon Quantum Dots within the FAPbI3 Active Layer

Advanced Energy Materials, Volume 15, Issue 36, September 23, 2025.
A hybrid perovskite of FAPbI3 with surface‐engineered Si quantum dots (SiQDs, ≈2 nm) shows enhanced carrier transport, reduced surface defects, and modified Fermi level and bandgap. SiQDs are mostly integrated within the perovskite film, and the perovskite lattice serves as a scaffold for the integration of the QDs.

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 ...
