摘要: Due to the required high reliability of many responsible engineering constructions structural health monitoring (SHM) systems must work in on-line mode. Therefore, it is necessary develop new fault detection techniques for improving faults detectibility and simultaneously reduce processing time detection. In present paper crack identification technique based on fractal dimension composite beams was discovered. For analysis finite element method (FEM)-based simulation modal data were considered. The obtained normal modes beam estimated Higuchi’s algorithm. Next, displacement noised with various levels simulating real measurement conditions determined depths. Obtained results show that proposed could be used practical SHM due its noise robustness, simplicity low time-consuming processing. Key-words: detection, polymeric composites, dimension, monitoring, diagnostics.
