Abstract

The rapidly growing industry of composite materials requires fast and accurate tools to check the quality of the composite parts during manufacturing and maintenance. To detect the defects, many non-destructive testing techniques exist. In this paper, authors are aimed at the improvement of one of the most promising techniques - Local Defect Resonance (LDR) detection with scanning Laser Doppler Vibrometry. A concept for the simulation-assisted testing procedure is proposed. Modal analysis is performed on several woven composite plates containing flat bottom holes and delamination of different defect sizes and depth. With the automated simulation process, more than 23000 simulations have been done to assess a wide range of possible defects. As an outcome of such simulations, a function of the LDR frequencies is defined for various defects and materials. Obtained database of mode shapes with and without clearly visible LDR is proposed as a simulation-based training in Deep Learning techniques, such as Convolutional Neural Networks, to increase defect detectability and to simplify the experimental setup.
