ANALYSIS OF YOUNG MODULUS AND POISSON RATIO USING I-KAZ 4D ANALYSIS METHOD THROUGH PIEZOFILM SENSOR

An alternative advanced statistical analysis method known as the I-kaz 4D or I-kaz 4 channels which using the sensor fusion concept by using four sensors to collect the vibration signals that excited by the impact hammer was introduced in this study. Mechanical properties of the material like Young Modulus and Poisson Ratio were obtained. The study carried for 2 types of metals i.e. copper and stainless steel. The specimens were in shape of circular, rectangular and square, where more material mechanical properties were obtained due to the variety of specimen shapes. The impact hammer used for the impact force with the range of different forces. The four piezofilm sensors have been placed on specimen surface to observe and record the vibration signal after the impact. The dynamic response technique also was used in this study and the obtained results been compared with the results obtained by I-kaz 4D method. Finally, correlation between I-kaz 4D coefficient and regression value being done to verify the result and justify the findings. The error for Young Modulus was 2.962% while Poisson Ratio was 1.000%. The study adhered to ASTM E1876 standard.
