POSTBUCKLING OF NANOCOMPOSITE PLATE REINFORCED WITH RANDOMLY ORIENTED AND DISPERSED CNTS MODELED THROUGH RSA TECHNIQUE
Краткое описание
The aim of the present paper is to study the buckling and postbuckling behavior of carbon nanotube (CNT)-reinforced magnesium (Mg) nanocomposite plates. A Boolean-based random sequential adsorption (RSA) technique is employed to model a representative volume element (RVE) with randomly oriented and positioned CNTs using uniform and normal distributions. The elastic properties of the resulting nanocomposite are evaluated using that RVE. Further, the evaluated stiffness properties of CNT-Mg nanocomposite are utilized to investigate the effects of CNT reinforcement on buckling and postbuckling behavior of the nanocomposite plate. Buckling and postbuckling studies of the nanocomposite plate are carried out using nonlinear finite element methods formulation based on the first-order shear deformation theory and von Karman's assumptions. The arc-length method is utilized to solve the resulting nonlinear finite-element algebraic equations. It is concluded that CNT reinforcement leads to substantial increase in the stiffness properties of soft matrix materials as compared to the stiff matrix materials, and hence percentage enhancements in buckling load and postbuckling strength of CNT-reinforced soft matrix materials are found to be more pronounced than those of CNT-reinforced stiff matrix materials.
