| Popis: | It is important to find an easy and efficient way of finding the tensile strength of the alloys by detecting the crack development in alloys. In the present project by having used fourteen samples of Al-SiC composite pieces the energy discharge during the cracks were found out. The Acoustic Emission technique was used in this experiment. The tensile testing was achieved by tensile loading on a 100 kN universal testing machine. The values obtained using the parameters such as hits; Felicity Ratio and Rise Angle were fed into the Artificial Neural Network. The network could foresee the errors at the rate of 3.125%, – 3.515% and −2.73% of hits, felicity ratio and rise angle respectively. Among these the value −2.73% seems to be the best while using Acoustic Emission technique. Though all the three have demonstrated significantly the value obtained using the Rise Angle can be taken as the best, since it is closer to the ideal error value ‘zero’. |
