This paper presents an analytical study on the dynamic stability of carbon nanotubes (CNTs) reinforced functionally graded composite beams when subjected to axial excitation loading. The are using a I-type CNTs reinforcement. section properties non-uniform assessed Halpin–Tsai model. analysis is performed by Bolotin’s method. Analytical expressions determining free vibration frequency, critical...

Multiple elastic inclusions with uniform internal stress fields in an infinite elastic matrix are constructed under given uniform remote in-plane loadings. The method is based on the sufficient and necessary condition imposed on the boundary value of a holomorphic function that guarantees the existence of the holomorphic function in a multiply connected region. The unknown shape of each of the ...

The analytical formulation of curved-plate non-linear equilibrium equations including transverse-shear-deformation effects is presented. The formulation uses the principle of virtual work. A unified set of non-linear strains that contains terms from both physical and tensorial strain measures is used. Linearized, perturbed equilibrium equations (stability equations) that describe the response o...

At the moment, Moshanir loading code which has been provided by Tavanir Company in 1998 is used for loading transmission line towers. Also ASCE52 are applied for designing these structures. In the above Moshanir loading code, loading parameters such as, maximum yearly ice thickness, maximum monthly ice thickness, maximum yearly wind speed and maximum monthly wind speed have been considered as ...

We address the problem of consensus control second-order nonholonomic systems via distributed under assumption that each vehicle receives measured states from a set neighbors, with bounded, time-varying, but non-differentiable delay. The controller we propose guarantees full consensus, in sense common point may be reached both Cartesian positions on plane and orientations all robots referred to...
