摘要: The paper investigates changes in determinism of undamaged and cracked aluminium plates with respect to excitation frequencies. Harmonic frequencies corresponding structural resonances has been used vibrate the plates. Vibration responses have analysed using recurrence plots quantification analysis. smallest sufficient embedding dimension estimated false nearest neighbour’s algorithm. Mutual information analysis applied determine relevant time delays. results demonstrate that performed indicates dynamic behaviour various crack modes.
