Özet

In this study, the buckling behavior of carbon nanotube (CNT) reinforced polymer rectangular plates in thermal environments under in-plane compressive load in the longitudinal direction is investigated. First, the micromechanical properties of polymers reinforced with carbon nanotubes are modeled. After establishing the constitutive relationships of nanocomposite plates with temperature-dependent material properties, based on the Kirchhoff-Love assumption, the stability and compatibility equations are derived. By choosing the approximation functions for simply-supported boundary conditions, the basic diferantial equations are solved, and a closed-form solution is obtained for the critical load in thermal environments. Based on this expression, the minimum value of the dimensionless critical load is obtained numerically depending on the buckling mode. Numerical analysis are performed for different temperature, volume fractions and CNT patterns.
