Supersonic flutter analysis of flat composite panels by unified formulation
S Natarajan, G Manickam, AJM Ferreira +1
In this paper, the linear flutter characteristics of laminated composite flat panels immersed in a supersonic flow is investigated using field consistent elements within the framew…
Smoothed Finite Element and Genetic Algorithm based optimization for Shape Adaptive Composite Marine Propellers
Manudha T Herath, Sundararajan Natarajan, B Gangadhara Prusty +1
An optimization scheme using the Cell-based Smoothed Finite Element Method (CS-FEM) combined with a Genetic Algorithm (GA) framework is proposed in this paper to design shape adapt…
Finite element computations on quadtree meshes: strain smoothing and semi-analytical formulation
Sundararajan Natarajan, Ean Tat Ooi, Hou Man +1
This short communication discusses two alternate techniques to treat hanging nodes in a quadtree mesh. Both the techniques share similarities, in that, they require only boundary i…
Displacement based finite element formulations over polygons: a comparison between Laplace interpolants, strain smoothing and scaled boundary polygon formulation
Sundararajan Natarajan, Ean Tat Ooi, Irene Chiong +1
Three different displacement based finite element formulations over arbitrary polygons are studied in this paper. The formulations considered are: the conventional polygonal finite…

Hygrothermal effects on free vibration and buckling of laminated composites with cutouts
Sundararajan Natarajan, Pratik S Deogekar
The effect of moisture concentration and the thermal gradient on the free flexural vibration and buckling of laminated composite plates are investigated. The effect of a centrally…
A parametric study on the buckling of functionally graded material plates with internal discontinuities using the partition of unity method
S Natarajan, S Chakraborty, M Ganapathi +1
