Abstract
Through the use of continuum mechanics, the static governing differential equation was used as an algorithm to detect delamination in composite plates. The algorithm outcome indicated whether or not the structure contained discontinuity through the presence of a residual term. The parameters of the algorithm were defined as the measured in-plane stain values, where a Savitzky-Golay (SG) filter was then used to process the governing differential equation. This paper presented a theoretical study into the use of this algorithm with an array of embedded fibre Bragg grating strain sensors. The measured inplane strains were obtained using a finite element analysis (FEA) study for a cantilever plate modelled in ANSYS Mechanical 18. This study investigated various delamination sizes ranging from 25 to 75 mm2 and the spaces between the fibre optic array consisting of 10, 20 and 40 mm. The measured strain values will be obtained from the FEA simulation through multiple ‘Construction Geometry Paths’ to illustrate the potential strain that the fibres could measure.
