An Explicit, Compact, and Rotation‐Agnostic Formulation for Equivalent Nodal Loads for Point‐Loaded Beams

International Journal for Numerical Methods in Engineering, Volume 127, Issue 7, 15 April 2026.
ABSTRACT In time‐marching dynamical simulations, treatment of contact forces in deformable bodies represented by finite element meshes requires a compromise between simulation fidelity and computational costs. External forces directly evaluated at the mesh nodes offer better computational performance at the cost of modelling fidelity.

General Conversion between ANCF and B-spline Surfaces

CoRR
In this paper, general conversion equations are derived between Absolute Nodal Coordinates Formulation (ANCF) finite surface elements and B-spline surfaces, an extension of our previous work on the conversion between ANCF cable elements and B-spline curves.

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.
