| The theory of studying the Carbon nanotube (CNT) technology was first introduced in 1991 and it is still under researches and developments. The significance of the Carbon nanotubes (CNTs) is that, their amazing strength, conductivities, and the various ways in which their molecules can be formed and arranged. Therefore, Carbon nanotubes are becoming very important components in the following many fields and applications such as oscillators, charge detectors, clocks, emission devices, sensors, and composites.;The aim of this thesis work is to develop a model for CNT reinforced composite structure based on the continuum approach.;This thesis is explaining in detailed the full procedure of getting the wave model for the CNTs using the averaging method for embedded CNT mixture composites. This procedure included the subsequent steps. First of all is finding the two cylindrical coordinate momentum equations in addition to the constitutive relations for each component in the composite. Then, assessing the symmetry conditions, and evaluating the continuity of the stresses, shears, and deformations around the composite radius. After that, averaging the momentum equations and deriving the relevant partial differential equations that describe the system in terms of the interactions term (&zgr; and S) and axial displacements (u), which also acquires finding the radial dependence of the shear stress and the radial displacement. Followed by applying the interface continuity and symmetry conditions for the stresses again along the composites in order to eliminate the stress and get the strains relations along the composites. Subsequently, this will lead to the final equations that describe the composite behavior. |
