MATHICSE Technical Report : Fast and accurate elastic analysis of laminated composite plates via isogeometric collocation and an equilibrium-based stress recovery approach [PDF]

A novel approach which combines isogeometric collocation and an equilibriumbased stress recovery technique is applied to analyze laminated composite plates. Isogeometric collocation is an appealing strong form alternative to standard Galerkin approaches,

Shape Gradient Computation in Isogeometric Analysis for Linear Elasticity [PDF]

, 2012
The transfer of geometrical data from CAD (Computer Aided Design) to FEA (Finite-Element Analysis) is a bottleneck of automated design optimization procedures, yielding a loss of accuracy and cumbersome software couplings.

Advanced Vibroacoustic Simulations Using Isogeometric Analysis

Engineering Proceedings
This work presents a methodology for integrating Computer-Aided Design (CAD), specifically using Rhinoceros 6, with Isogeometric Analysis (IGA) for vibroacoustic simulations. Since CAD models typically provide only boundary representations, the 3D domain

Stability of rectangular tunnels in cohesive-frictional soil under surcharge loading using isogeometric analysis and Bayesian neural networks

This study evaluates the stability of rectangular tunnels in cohesive-frictional soils under surcharge loading using a combination of IsoGeometric Analysis and artificial neural networks. A dataset of 12,946 samples was generated automatically to analyze

Isogeometric analysis of shells

, 2014
This work is concerned with the isogeometric analysis of shells. A new hierarchic family of NURBS-based shell finite elements is developed. Besides a shear-rigid 3-parameter shell element formulation with Kirchhoff-Love kinematics, both a shear flexible 5-parameter Reissner-Mindlin-type and a 7-parameter 3D shell element which accounts for thickness ...

STRUCTURAL SHAPE OPTIMIZATION BY ISOGEOMETRIC BOUNDARY ELEMENT METHOD

Jixie qiangdu, 2019
In Isogeometric boundary element method（IGA-BEM）, Non-Uniform Rational B-Splines（NURBS） which are used for describing the geometric boundary in a computer-aided geometric design（CAGD） are employed as shape functions of Boundary Element Method.
