| Abstract: | The relationship between acoustic velocity and elastic constant has been repre-sented.The foundamental principle of pulse overlapping technique for acoustic ve-locity examination has been briefly expressed.The results of measurement for se-veral typical ceramic materials have been given and an error analysis has beencarried out.It can be confirmed that the ultrasonic technique is adequate to elasticconstant measurement for ceramic materials and has many advantages,such as littledemand upon materials for specimen preparation,nondestructive character andexcellent repeatability of measurement. |
