VIBRO-ACOUSTIC METHOD FOR DIAGNOSTICS OF MECHANICAL DEFECTS OF CONSTRUCTIONAL MATERIALS

摘要

A vibro-acoustic method for diagnostics of mechanical defects of constructional materials is in registration of changes of acoustic characteristics of material because of generation and development of mechanical defects of different origin. Quantitative and qualitative composition of defects in material is determined by the change of its vibro-acoustic characteristics in audio region of acoustic spectrum.
