Strain smoothing in FEM and XFEM
Stéphane Bordas,Timon Rabczuk,Nguyen-Xuan Hung,Vinh Phu Nguyen,Sundararajan Natarajan,Tino Bog,Do Minh Quan,Nguyen Vinh Hiep +7 more
TL;DR: The numerical results indicate that for 2D and 3D continuum, locking can be avoided and the principle is extended to partition of unity enrichment to simplify numerical integration of discontinuous approximations in the extended finite element method.
Journal ArticleDOI
NURBS-based finite element analysis of functionally graded plates: Static bending, vibration, buckling and flutter
N. Valizadeh,Sundararajan Natarajan,Octavio Andrés González-Estrada,Timon Rabczuk,Tinh Quoc Bui,Stéphane Bordas +5 more
TL;DR: In this article, a non-uniform rational B-spline based iso-geometric finite element method is used to study the static and dynamic characteristics of functionally graded material (FGM) plates.
Journal ArticleDOI
Size-dependent free flexural vibration behavior of functionally graded nanoplates
TL;DR: In this paper, size dependent linear free flexural vibration behavior of functionally graded (FG) nanoplates using the iso-geometric based finite element method was investigated using non-uniform rational B-splines.
Journal ArticleDOI
An adaptive singular ES-FEM for mechanics problems with singular field of arbitrary order
Hung Nguyen-Xuan,Hung Nguyen-Xuan,Gui-Rong Liu,Stéphane Bordas,Sundararajan Natarajan,Timon Rabczuk +5 more
TL;DR: In this paper, a singular edge-based smoothed finite element method (sES-FEM) is proposed for mechanics problems with singular stress fields of arbitrary order, which uses a basic mesh of three-noded linear triangular (T3) elements and a special layer of fivenoded singular triangular elements (sT5) connected to the singular point of the stress field.
Journal ArticleDOI
Numerical integration over arbitrary polygonal domains based on Schwarz–Christoffel conformal mapping
TL;DR: Numerical results presented for a few benchmark problems in the context of polygonal finite elements show that the proposed method yields accurate results.
