SEM images of (a) aligned deposition of fiber cantilevers with superglue on one end and (b) tip end of the fiber showing brittle fracture.
(a) Experimental frequency response of a typical fiber cantilever (response measured at the tip of the fiber), with the natural frequencies circled. (b) Shaker response at the base of the fiber. (c) Corresponding first three mode shapes.
Comparison between analytical and experimental results of first three resonant modes for eight fiber cantilevers given in Table I for fixed-free boundary condition experiments. (● denotes analytical predictions and ◆, ◼, ▲ denote experimental values for , , and , respectivley.)
Geometrical data of the fabricated eight PMMA fiber cantilevers used in experiments.
