The vibration of post-buckled fluid-conveying pipe made functionally graded material is analyzed. properties are assumed to be in the thickness direction according power-law distribution. An exact solution obtained for post-buckling deformation with various boundary conditions. linear problem solved around first buckled configuration and natural frequencies three lowest modes obtained. influenc...
In the present study, nonlinear vibration of coupled carbon nanotubes (CNTs) in presence of surface effect is investigated based on nonlocal Euler-Bernoulli beam (EBB) theory. CNTs are embedded in a visco-elastic medium and placed in the uniform longitudinal magnetic field. Using von Kármán geometric nonlinearity and Hamilton’s principle, the nonlinear higher order governing equations are deriv...
This paper presents an exact analytical model for optimizing stability of thin-walled, composite, functionally graded pipes conveying fluid. The critical flow velocity at which divergence occurs is maximized for a specified total structural mass in order to ensure the economic feasibility of the attained optimum designs. The composition of the material of construction is optimized by defining t...
