Abstract
The paper deals with the free vibration analysis of nano-composite beams. The nano-composite beams are a combination of single walled carbon nano-tubes (SWCNT) as reinforcement fibre and are dispersed in the epoxy matrix. Material properties of the resulting nano-composite material are extracted using the Timoshenko beam theory. Finite element method (FEM) is employed to solve the governing equations of motion. The effect of various parameters such as boundary conditions, carbon nanotube (CNT) volume fraction, slenderness ratio and the distribution of nano-material on the natural frequency of the composite structure are studied and presented. The obtained results reveal that CNT volume fraction and distribution have substantial effect on the properties of the nano-composite beam.
