An Improved XFEM With Multiple High-Order Enrichment Functions and Low-Order Meshing Elements for Field Analysis of Electromagnetic Devices With Multiple …

N Duan, W Xu, S Wang, J Zhu, Y Guo – IEEE TRANSACTIONS ON MAGNETICS, 2015
This paper proposes an improved extended finite element method for modeling
electromagnetic devices with multiple nearby geometrical interfaces. In regions near these
interfaces, the magnetic vector potential approximation is enriched by incorporating 

THE MANDIBLE REMODELING INDUCED BY DENTAL IMPLANTS: A MESHLESS APPROACH

J BELINHA, L DINIS, RMN JORGE – Journal of Mechanics in Medicine and Biology, 2015
This work aims to evaluate the prediction efficiency of a recently developed numerical
approach in the mandible bone tissue remodeling process. The remodeling algorithm,
seeking the minimization of the strain energy density, includes a phenomenological 

Investigation of surface stress effect in 3D complex Nano parts Using FEM and modified boundary Cauchy-Born Method

R Ghaffari, K Alipour, S Solgi, S Irani, H Haddadpour – Journal of Computational …, 2015
Abstract In this paper the surface effects in 3D complex parts are investigated via classical
FEM and the modified boundary Cauchy-Born method, which are continuum based theories,
and the results are compared with molecular dynamics simulations. The Boundary 

A recovery-type a posteriori error estimator for gradient elasticity

ÜH Çalık-Karaköse, H Askes – Computers & Structures, 2015
Abstract In this paper, an a posteriori error estimator of the recovery type is developed for the
gradient elasticity theory of Aifantis. This version of gradient elasticity can be implemented in
a staggered way, whereby solution of the classical equations of elasticity is followed by 

A coupled IGA-meshfree discretization of arbitrary order of accuracy and without global geometry parameterization

N Valizadeh, Y Bazilevs, JS Chen, T Rabczuk – Computer Methods in Applied …, 2015
Abstract This article presents a novel approach for coupling of Isogeometric Analysis (IGA)
and Meshfree discretizations. Taking advantage of the strengths of both techniques, we
make IGA responsible for the representation of the exact geometry of the problem domain 

Divergence-conforming discretization for Stokes problem on locally refined meshes using LR B-splines

KA Johannessen, M Kumar, T Kvamsdal – Computer Methods in Applied Mechanics …, 2015
Abstract To solve the incompressible flow problems using isogeometric analysis, the div-
compatible spline spaces were originally introduced by Buffa et al.(2011)[10, 11], and later
developed by Evans (2011). In this paper, we extend the div-compatible spline spaces 

Control of spatially distributed processes with unknown transport‐reaction parameters via two layer system adaptations

DB Pourkargar, A Armaou – AIChE Journal, 2015
Abstract We consider the control problem of dissipative distributed parameter systems
described by semilinear parabolic partial differential equations with unknown parameters
and its application to transportreaction chemical processes. The infinite dimensional 

[PDF] Adaptive 2D IGA boundary element methods

M Feischl, G Gantner, A Haberl, D Praetorius – arXiv preprint arXiv:1504.06164, 2015
Abstract: We derive and discuss a posteriori error estimators for Galerkin and collocation IGA
boundary element methods for weakly-singular integral equations of the first-kind in 2D.
While recent own work considered the Faermann residual error estimator for Galerkin IGA 

[PDF] Isogeometric Analysis of Boundary Integral Equations

M Taus, GJ Rodin, TJR Hughes – 2015
Abstract Isogeometric analysis is applied to boundary integral equations corresponding to
boundary-value problems governed by Laplace’s equation. It is shown that the smoothness
of geometric parametrizations central to computer-aided design can be exploited for 

Real‐time haptic manipulation and cutting of hybrid soft tissue models by extended position‐based dynamics

J Pan, J Bai, X Zhao, A Hao, H Qin – Computer Animation and Virtual Worlds, 2015
Abstract This paper systematically describes an interactive dissection approach for hybrid
soft tissue models governed by extended position-based dynamics. Our framework makes
use of a hybrid geometric model comprising both surface and volumetric meshes. The fine
