Abstract

An algorithm has been developed to determine the full deformation field of a cantilever honeycomb plate under free-end loading conditions. The algorithm utilizes strain information from a set of sixteen fiber Bragg grating (FBG) sensors mounted on the plate so that all sensors measure strains along the clamped-free direction. The sensors are interrogated using a wavelength division multiplexing scheme, and measured strains are converted to full-field displacement. The algorithms used to interrogate the sensors, perform the strain-displacement calculations and generate a real-time (approximately 60 Hz) mesh of displacement values are encoded in a C program.
