| Abstract | ||
| This work presents a full-scale study of the structural behavior of nanoparticles reinforced nanocomposite porous beams under sinusoidal transverse dynamic force. Application of the Mori-Tanaka method for the assessment of the effective properties of the nanocomposite material takes into account the structure of nanoparticle arrangement as well as their interaction with the pores in the matrix. Consequently, the structural transverse behavior of the beams is modeled using Aydogdu shear deformation theory (ASDT) that provides a more accurate deformation extended through a refined shear deformation framework. By integrating the nonlinear strain displacement relations of the component using energy methods and Hamilton's principle, the governing equations are derived which incorporates the interactional and dynamic behavior of the structure. The displacement response of the beams is determined by using the Ritz method for the dynamic analysis of the structure. This paper establishes the impact of a number of key variables on the time varying behavior of nanocomposite porous beams. Among them are the volume concentration of nanoparticles, porosity, effects of the localized aggregation of nanoparticles, geometric characteristics of the beams, and the boundary conditions. The findings also show that an increase in the percentage volume fraction of nanoparticles reduces the dynamic displacement, proving the durability offered by nanoparticle reinforcement for structural applications. Furthermore, the effects of porosity and nanoparticle agglomeration as well as design parameters on the dynamic behavior of the developed material are also investigated. | ||
