Abstract
Interest has been shown in the problem of real-time crack detection, crack extent measurement and the identification of the impact source causing the damage. A solution to the problem of impact source identification is presented using a signal processing technique employing piezoelectric sensors. In order to detect the crack and to identify the source of the impact, the Fuzzy logic approach is suggested. Based on the FLA approach, a procedure to develop the rule base is given. The implementation of the rules is done using Hardware Description Languages (HDL) such as Verilog. The procedure from Verilog to VLSI implementation is suggested. FPGA implementation and testing of the suggested procedure is included. The problems for the future work on the development of VLSI to measure the crack and identify the impact sources are given.
