Size effects in nanostructured Li-ion battery cathode particles

Journal of the Mechanical Behavior of Materials, 2020
Cathode materials for Li-ion batteries exhibit volume expansions on the order of 10% upon maximum lithium insertion. As a result internal stresses are produced and after continuous electrochemical cycling damage accumulates, which contributes to their ...

NURBS-Based Parametric Design for Ship Hull Form

Journal of Marine Science and Engineering, 2022
Recently, the NURBS technique has been widely used in the 3D design software for ships. However, in most research, the NURBS technique is only applied to the mathematical representation of hull curves and surfaces, and the parametric deformation of hull ...

Isogeometric Resolution of the Brinkman-Forchheimer-Darcy [PDF]

Journal of Applied and Computational Mechanics
In this paper, we employ the finite element method based on non-uniform rational B-splines function approximation to solve the nonlinear Brinkman-Forcheimer-Darcy equation in a simply connected and bounded Lipschitz domain Ω.

A Feedrate Planning Method for the NURBS Curve in CNC Machining Based on the Critical Constraint Curve

Applied Sciences, 2021
The curvature of the NURBS curve varies along its trajectory, therefore, the commonly used feedrate-planning method, which based on the acceleration/deceleration (Acc/Dec) model, is difficult to be directly applied in CNC machining of a NURBS curve.

NURBS or not NURBS?

Comptes Rendus. Mathématique, 2016
The view adopted here is that the largest class of splines which are useful for design is composed of all spaces of geometrically continuous piecewise quasi-Chebyshevian splines that contain constants and possess blossoms. We recently described an iterative construction of all spaces of this class.

Fast Reconstruction Model of the Ship Hull NURBS Surface with Uniform Continuity for Calculating the Hydrostatic Elements

Journal of Marine Science and Engineering, 2023
The fast reconstruction of the ship hull nonuniform rational B-spline (NURBS) surface with uniform continuity is essential for calculating hydrostatic elements such as waterplane area and molded volume in real time.
