摘要: Abstract Functionally graded materials (FGMs) and fluid-conveying nanopipes may find significant applications in nanotechnology. In this paper, the size-dependent free vibration stability of multi-span viscoelastic FGM conveying fluid are investigated by nonlocal elasticity theory. And a hybrid method which combines reverberation-ray matrix wave propagation is developed to determine natural frequencies. Present analysis verified comparing results with those existing literature. Then, effects velocity, parameter, volume fraction exponent internal damping on discussed. It found that decreases increase parameter increases increasing exponent. also distributions frequencies can be modulated designing
