Free vibration study of composite conical panels reinforced with FG-CNTs
Engineering Structures, 2018Abstract This work analyses the natural frequencies of composite conical panels made of a polymeric matrix reinforced with uniform or functionally graded carbon nanotubes (FG-CNTs). The mechanical properties of the composite conical panels rely on a refined rule of mixtures, including some efficiency parameters, whereas the kinematics of the problem ...

On the nonlinear dynamics of bimodular laminated composite conical panels
Nonlinear Dynamics, 2014The nonlinear dynamics of bimodular laminated composite conical panels subjected to harmonic excitation is investigated using Bert’s constitutive model and first-order shear deformation theory based finite element. The governing equations of motion are solved to obtain the state vector representing the periodic response by employing shooting technique ...

Free vibration of FGM Lévy conical panels
Composite Structures, 2014Abstract Free vibration analysis of open conical panels made of through-the-thickness functionally graded materials (FGMs) is analyzed in this research. Mechanical properties of the shell are distributed across the thickness based on the power law function.

Dynamic characteristics of truncated conical panels made of FRPs reinforced with agglomerated CNTs
Structures, 2021Abstract This paper studies the free and forced vibration characteristics of laminated truncated conical panels made of fiber-reinforced polymers (FRPs) filled with carbon nanotubes (CNTs) and surrounded by an elastic foundation. The panel is composed of low-density polymer enriched with randomly oriented agglomerated CNTs as well as oriented ...

Large Amplitude Nonlinear Heat-Induced Vibrations of Temperature-Dependent FGM Conical Panels
International Journal of Structural Stability and DynamicsThis research deals with the large amplitude vibrations in a conical panel under the action of sudden temperature elevation. The conical panel is made of functionally graded materials where properties vary through the thickness direction. All of the properties are considered to be temperature-dependent for the constituents.

Hygro-thermo-mechanical analysis of fiber-steered composite conical panels
Composite Structures, 2017Abstract Automated fiber placement (AFP) is one of the recently developed robot-assisted composite manufacturing techniques. Steering fibers along optimal curvilinear paths enables tailoring the multifunctional properties of laminated composites to fully exploit all potentials of composite materials.

Buckling of functionally graded conical panels under mechanical loads
Composite Structures, 2012Abstract This paper presents an analytical approach to investigate the linear buckling of truncated conical panels made of functionally graded materials and subjected to axial compression, external pressure and the combination of these loads. Material properties are assumed to be temperature-independent, and graded in the thickness direction ...

Buckling analysis of cross-ply laminated conical panels using GDQ method
Composites Part B: Engineering, 2013Abstract The buckling analysis of cross-ply laminated conical shell panels with simply supported boundary conditions at all edges and subjected to axial compression is studied. The conical shell panel is a very interesting problem as it can be considered as the general case for conical shells when the subtended angle is set to 2π and also cylindrical
