A Simple-FSDT-Based Isogeometric Method for Piezoelectric Functionally Graded Plates

open access: yesMathematics, 2020
An efficient isogeometric analysis method (IGA) based on a simple first-order shear deformation theory is presented to study free vibration, static bending response, dynamic response, and active control of functionally graded plates (FGPs) integrated ...

Optimal-order isogeometric collocation at Galerkin superconvergent points

open access: yes, 2016
In this paper we investigate numerically the order of convergence of an isogeometric collocation method that builds upon the least-squares collocation method presented in [1] and the variational collocation method presented in [2].

Sensitivity analysis of non-uniform rational B-splines–based finite element/boundary element coupling in structural-acoustic design

open access: yesFrontiers in Physics
For the purpose of modeling the acoustic fluid-structure interaction using direct differentiation method and conducting a structural-acoustic sensitivity analysis, a coupling approach based on the finite element method and the fast multipole boundary ...

Towards the isogeometric aero-engine

open access: yesResults in Engineering, 2023
Creating very detailed finite element models of aero-engines is a very time-consuming process especially if structured meshes have to be generated for thousands of parts.

BDDC Deluxe for Isogeometric Analysis [PDF]

open access: yes, 2016
The main goal of this paper is to design, analyze, and test a BDDC (Balancing Domain Decomposition by Constraints, see [12, 23]) preconditioner for Isogeometric Analysis (IGA), based on a novel type of interface averaging, which we will denote by deluxe scaling, with either full or reduced set of primal constraints.

Volumetric spline parameterization for isogeometric analysis [PDF]

open access: yesComputer Methods in Applied Mechanics and Engineering, 2020
Given the spline representation of the boundary of a three dimensional domain, constructing a volumetric spline parameterization of the domain (i.e., a map from a unit cube to the domain) with the given boundary is a fundamental problem in isogeometric analysis.

Isogeometric analysis based on geometric reconstruction models

open access: yesFrontiers of Mechanical Engineering, 2021
In isogeometric analysis (IGA), the boundary representation of computer-aided design (CAD) and the tensor-product non-uniform rational B-spline structure make the analysis of three-dimensional (3D) problems with irregular geometries difficult.
