Journal ArticleDOI
Efficient recovery-based error estimation for the smoothed finite element method for smooth and singular linear elasticity
Octavio Andrés González-Estrada,Sundararajan Natarajan,Juan José Ródenas,Hung Nguyen-Xuan,Stéphane Bordas +4 more
TL;DR: An error control technique aimed to assess the quality of smoothed finite element approximations is presented in this paper, and a recovery type error estimator based on an enhanced recovery technique is proposed.
Journal ArticleDOI
Adaptive phase field modelling of crack propagation in orthotropic functionally graded materials
TL;DR: In this article, the authors extended the adaptive phase field method to model fracture in orthotropic functionally graded materials (FGMs) and employed a recovery type error indicator combined with quadtree decomposition for adaptive mesh refinement.
Journal ArticleDOI
A unified polygonal locking-free thin/thick smoothed plate element
Irwan Katili,Imam Jauhari Maknun,Andi Makarim Katili,Stéphane Bordas,Stéphane Bordas,Stéphane Bordas,Sundararajan Natarajan +6 more
TL;DR: In this paper, a cell-based smoothed finite element method is proposed for thin and thick plates based on Reissner-Mindlin plate theory and assumed shear strain fields.
Journal ArticleDOI
Scaled boundary polygons for linear elastodynamics
TL;DR: In this paper, a polygonal scaled boundary finite element method (SBFEM) is proposed for linear elastodynamics in two dimensions, where the domain is divided into non-overlapping polygon-al elements, and the scaled-boundary finite element approach is employed over each polygon.
Journal ArticleDOI
A fully smoothed XFEM for analysis of axisymmetric problems with weak discontinuities
TL;DR: A fully smoothed extended finite element method for axisymmetric problems with weak discontinuities by combining the Gaussian divergence theorem with the evaluation of indefinite integral based on smoothing technique, which is used to transform the domain integral into boundary integral.
