N2 - The paper presents applications of Impulse Resonant Acoustic Spectroscopy (IRAS) for reliable detection of early stages of fracture, fatigue and other damage, as well as investigation of structure-sensitive acoustical signatures for fundamental material research. The experimental investigations were conducted on steel samples and bricks under different types of loading in laboratory conditions and in the field on the wall of a blast furnace. A special effort was made to investigate the changes of acoustical response during loading and after aging of materials, but before a warning of damage (necking, crack initiation, "crazing, disbonding, surface flow, and etc.) is physically observed in service life. Measurements were made periodically as structural damage accumulated, but no visible surface crack formation was observed during the tests. The described techniques can be used for the assessment of structure integrity, remaining life and adjustment of maintenance schedules in applications as diverse as reactor containment wall damage, inspection of damage in buildings, bridges, furnaces, pipelines, aging aircraft, et cetera. Acoustical techniques, Material research, Damage accumulation.
