PEMANFAAT FREKUENSI BUNYI MATERIAL SEBAGAI DASAR PENGUJIAN MODULUS ELASTISITAS PADA PENGUJIAN TANPA MERUSAK (NON DESTRUCTIVE TEST)

Abstract

Elastic modulus of material are usually obtained from tensile test. Tensile test categorized as destructive test. One of destructive test weakness is the testing specimen can not be reused. So we need alternative on elastic modulus test without damaging the specimen (non destructive test). This research aims to determine whether the sound frequency of material can be used as a basic for elastic modulus test as a non destructive test.
