Buckling Analysis of Carbon Nanotube (Cnt) Reinforced Laminated Composite Panels with Holes

Abstract

This research offers a thorough examination employing both analytical and computational approaches to ascertain the buckling load of composite plates reinforced with carbon nanotubes (CNTs). The primary goal of this research is to understand and anticipate the buckling effects of composite plates reinforced by carbon nanotubes (CNTs). To achieve this goal, the researchers first analyze the effect of carbon nanotubes (CNTs) on the material's mechanical properties and their influence on elastic properties. Subsequently, the buckling load is analytically computed employing the Classical Laminated Plate Theory (CLPT). Subsequently, numerical methodologies, particularly the finite element method, are utilized to compute the buckling load. The developed computational model is then rigorously validated through comparison with analytical results. Once the model's validation is established, a series of parametric analyses are conducted, encompassing both unperforated and perforated plates. Furthermore, the outcomes of this research are used to provide secondary validation for perforated plates by comparing the findings to those available in the literature. The parametric analyses unveil the diverse effects of variables such as the CNT reinforcement ratio, matrix material properties, stacking lay-up, and hole diameter on the buckling load.
