Acoustic Emission and Modal Frequency Variation in Concrete Specimens under Four-Point Bending

Acoustic Emission and Modal Frequency Variation in Concrete Specimens under Four-Point Bending

The Acoustic Emission (AE) and Dynamic Identification (DI) techniques were applied simultaneously, in an original way, to examine the stress dependent damage progress in pre-notched concrete beams tested in four-point bending. The damage mechanisms were characterized by analyzing the AE signals regi...
