Free vibration and mechanical buckling of plates with in-plane material inhomogeneity - a three dimensional consistent approach
Tingsong Xiang, Sundararajan Natarajan, Hou Man +2
In this article, we study the free vibration and the mechanical buckling of plates using a three dimensional consistent approach based on the scaled boundary finite element method.…
Assessment of certain higher-order structural models based on global approach for bending analysis of curvilinear composite laminates
Anand Venkatachari, Sundararajan Natarajan, K Ramajeyathilagam +1
In this paper, the performance of different structural models based on global approach in evaluating the static response of curvilinear fibre composite laminates is analyzed. A Co…
Panel flutter characteristics of sandwich plates with CNT reinforced face sheets using an accurate higher-order theory
A Sankar, S Natarajan, M Haboussi +2
In this paper, the flutter characteristics of sandwich panels with carbon nanotube (CNT) reinforced face sheets are investigated using QUAD-8 shear flexible element developed based…
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…
Numerical evaluation of stress intensity factors and T-stress for interfacial cracks and cracks terminating at the interface without asymptotic enrichment
Sundararajan Natarajan, Chongmin Song, Salim Belouettar
In this paper, we extend the recently proposed extended scaled boundary finite element method (xSBFEM)~\cite{natarajansong2013} to study fracture parameters of interfacial cracks a…
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…
