On the equivalence between the cell-based smoothed finite element method and the virtual element method
Sundararajan Natarajan, Stéphane P. A. Bordas, Ean Tat Ooi
We revisit the cell-based smoothed finite element method (SFEM) for quadrilateral elements and extend it to arbitrary polygons and polyhedrons in 2D and 3D, respectively. We highli…

A hybrid T-Trefftz polygonal finite element for linear elasticity
Kalyan Bhattacharjee, Sundararajan Natarajan, Stephane Bordas
In this paper, we construct hybrid T-Trefftz polygonal finite elements. The displacement field within the polygon is repre- sented by the homogeneous solution to the governing diff…
