of the material are regarded as one of the most significant aspects of the process.
This is to prevent any component or structure failure. This study employs the
implementation of a newly devised method for characterising the property of
a material based on the non-destructive testing concept which uses vibrational
signals. Experimental procedure was carried out by elastically triggering a
specimen using an impact hammer following ASTM C 1259-01 standard within the
specific range of impact force. The polymer material specimen tested were of
four types: Polycarbonate (PC), Polyoxymethylene (POM), Polyvinyl chloride (PVC)
and Cast nylon (MC). Data obtained involved three forms of signals which are
vibrational signals recorded by accelerometer sensor, the vibration signal recorded
by piezofilm sensor and the impact force signal using the impact hammer. An
alternative statistical analysis of Integrated Kurtosis-Based Algorithm for
Z-Filter (I-kaz™) method was used to analyse and interpret the time
domain of vibrational signal obtained from the experiment. The results are two
correlation processes between the material properties (Bulk modulus and hardness-Vickers)
and the I-kaz™, Z^{8 }coefficients of vibration signal that
are recorded by the piezofilm sensor and accelerometer sensor. The findings
prove that there is a relationship between the I-kaz™coefficients
of vibration signal and the properties of certain materials based on statistical
analysis approach used in this study.]]>Groves, D. and J.B. Wachtman Jr.,1986Tan, M.H.M.A., F. Mat, I.M.A. Rahim, N.T. Lile and S. Yaacob,2011Bunshan, R.F.,1971Young, W. and R.
