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.
Journal ArticleDOI
A spectral finite element model for analysis of axial–flexural–shear coupled wave propagation in laminated composite beams
TL;DR: In this paper, a spectral finite element model (SFEM) for analysis of axial-flexural-shear coupled wave propagation in thick laminated composite beams is presented, which is suitable for structural diagnostics and broad-band wave propagation problems.
Journal ArticleDOI
On the performance of strain smoothing for quadratic and enriched finite element approximations (XFEM/GFEM/PUFEM)
Stéphane Bordas,Stéphane Bordas,Sundararajan Natarajan,Pierre Kerfriden,Pierre Kerfriden,Charles E. Augarde,D. Roy Mahapatra,Timon Rabczuk,Stefano Dal Pont +8 more
TL;DR: In this article, Chen et al. extended the strain smoothing to higher order elements and investigated numerically in which condition strain-smoothing is beneficial to accuracy and convergence of enriched finite element approximations.
Journal ArticleDOI
Graphene Oxide—A Tool for the Preparation of Chemically Crosslinking Free Alginate–Chitosan–Collagen Scaffolds for Bone Tissue Engineering
Elayaraja Kolanthai,Pugazhendhi Abinaya Sindu,Deepak Kumar Khajuria,Sarath Chandra Veerla,Dhandapani Kuppuswamy,Luiz Henrique Catalani,D. Roy Mahapatra +6 more
TL;DR: The potential use of GO to prepare free SA-CS-Col scaffolds with preserved porous structure with elongated Col fibrils is indicated and these composites, which are biocompatible and stable in a biological medium, could be used for application in engineering bone tissues.
Book
Spectral Finite Element Method: Wave Propagation, Diagnostics and Control in Anisotropic and Inhomogeneous Structures
TL;DR: In this paper, a theory of anisotropic and inhomogenous materials and solution techniques for wave propagation in one-dimensional and two-dimensional inhomogeneous materials is presented.
