(a) normalized amplitude; and (b) phase of the system dynamic response versus the normalized harmonic frequency for a damping ratio of 0.1. (c) geometry of the cantilever beams; (d) computational domain of the V-shaped cantilever with added mass; (e) “deformed shape” representation of the total displacement when the structure is subject to a vertical acceleration at 5 Hz; (f) numerical responsivity in amplitude of the OF sensor; and (g) numerical responsivity of the phase of the OF sensor.
