Effect of different geometrically nonlinear strain measures on the static nonlinear response of isotropic and composite shells with constant curvature
A. Pagani, R. Azzara, B. Wu +1
The structural analysis of ultra-lightweight flexible shells and membranes may require the adoption of complex nonlinear strain-displacement relations. These may be approximated an…
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…
Static bending and free vibration of cross ply laminated composite plates using NURBS based finite element method and unified formulation
S Natarajan, H Nguyen-Xuan, AJM Ferreira +1
This paper presents an effective formulation to study the response of laminated composites based on isogeometric approach (IGA) and Carrera unified formulation (CUF). The IGA utili…
Analysis of functionally graded material plates using triangular elements with cell-based smoothed discrete shear gap method
S Natarajan, AJM Ferreira, S Bordas +3
In this paper, a cell based smoothed finite element method with discrete shear gap technique is employed to study the static bending, free vibration, mechanical and thermal bucklin…
