Bending and vibration study of carbon nanotubes reinforced functionally graded smart composite beams

Abstract A study of smart functionally graded (FG) beams made carbon nanotube (CNT) reinforced composites combined with piezoelectric materials is presented. The material parameters the composite are assumed to vary along their thickness following extended rule mixture. finite element (FE) model was developed for FG nanotube-reinforced beam materials. This tested against previously published studies and found be in accordance them. numerical results were evaluated using various boundary conditions appropriateness layer deflection control presented followed by free vibration results. analysis revealed that efficiently controlled bending deflections presently studied beams. Various profiles grading considered
