This work studies the vibration of sandwich beams reinforced with carbon nanotubes (CNTs) under moving point loads. The cores of the beams are homogeneous while their two sides are made of carbon nanotube reinforced composites. The effective properties of two face sheets are estimated through a micromechanical model. A uniform distribution (UD) and four different types of functionally graded (FG) distributions, namely FG-X, FG, FG-V, FG-O, are considered. |
