Acoustic Emission is not only expected as a non-destructive evaluation technique in practice but also noted as a new powerful means of evaluation of materials. AE occurs with plastic deformation and propagation of crack, and this patterns of occurence of AE vary with materials. AE which comes from propagation of crack depends on the shapes and properties of materials. Like this AE has characteristic of material. The present work is an attempt to evaluate characteristics of carbon steel(SM55C)and Die steel(SKD11)by means of dynamic response of AE method.
