Analysis of cross-ply laminated plates using isogeometric analysis and unified formulation
Curved and Layered Structures, 2014 In this paper, we study the static bending and free vibration of cross-ply laminated composite plates using sinusoidal deformation theory. The plate kinematics is based on the recently proposed Carrera Unified Formulation (CUF), and the field variables ...

NURBS-Based Isogeometric Analysis Method Application to Mixed-Mode Computational Fracture Mechanics [PDF]
Journal of Applied and Computational Mechanics, 2019 An interaction integral method for evaluating mixed-mode stress intensity factors (SIFs) for two dimensional crack problems using NURBS-based isogeometric analysis method is investigated. The interaction integral method is based on the path independent J-

Analysis of the Flow Field from Connection Cones to Monolith Reactors
Energies, 2019 The connection cones between an exhaust pipe and an exhaust after-treatment system (EATS) will affect the flow into the first monolith. In this study, a new streamlined connection cone using non-uniform rational B-splines (NURBS) is applied to optimize ...

An Isogeometric Analysis Approach to Kinematics of Spatial Rigid Multibody Systems with Imperfect Joints [PDF]
Modeling, Identification and Control, 2020 This paper proposes a novel generic methodology for kinematics of spatial rigid-multibody systems with and without lubricated joints. In this method CAD surface representations in the form of non-uniform rational B-splines (NURBS) are used to address the

A surrogate model based on Non-Uniform Rational B-Splines hypersurfaces
Procedia CIRP, 2018 Abstract This study aims at providing an original metamodeling technique based on the Non-Uniform Rational B-Splines (NURBS) formalism. The proposed approach is able to fit general non-convex sets of target points (TPs) by extending the NURBS formalism to the N-dimensional (N-D) case, getting in this way a general NURBS hypersurface.

Simulation of Seismic Response of Reinforced Concrete Beam-Column Joints with Nurbs Surface Fitting
Archives of Civil Engineering, 2017 This paper presents an approach based on NURBS (non-uniform rational B-splines) to achieve a seismic response surface (SRS) from a group of points obtained by using an analytical model of RC joints.
