“…Many methods have been developed for nondestructive evaluation, e.g. acoustic emission [1,2], infrared thermography [3] or ultrasonic testing [4][5][6][7]. Of particular interest are impact-echo techniques [8,9] and methods based on propagation of elastic waves [10,11].…”

This paper investigates inspection of reinforced concrete elements sensitive to the splitting failure. The behaviour of a reinforced concrete specimen subjected to a tensile stress is considered. The damage detection procedure is based on the ultrasonic wave propagation technique. The piezoelectric transducers are located on both ends of the specimen and the measurements are taken periodically during the incrementally increased loading. The features of measured signals in time and frequency domains as well as wavelet transforms before and after the splitting failure are studied. The experimental results show that proposed method can be used for monitoring of damage evolution in concrete elements. The method makes possible detection of the moment just before the splitting failure occurs.

“…The Acoustic emission (AE) technique is an effective non-destructive method that analyzes the characteristics of elastic waves that are caused by microscopic damage in the concrete member [1][2][3]; hence, the AE technique can be applied to different fields, such as rock masses failure monitoring [4], quality control of metal processing [5,6], and structural fatigue testing [7,8]. In the aforementioned fields, parameter analysis methods are often adopted to cope with the diversity and uncertainty of the generated signals [9].…”

Abstract. The paper deals with automated monitoring of damage evolution in concrete elements subjected to three-point bending tests. The monitoring is based on the nonlinear interactions of traveling ultrasonic waves with micro-crack zones inside the concrete specimens and surface-breaking cracks. The developed procedure assumes semi-continuous ultrasonic testing during the element full loading cycle and generation of the power spectral density maps for the on-line assessment of the degradation process. Two damage indicators are introduced to evaluate micro-and macro-damage. The preliminary experimental results show that the proposed automated monitoring system provides an effective method for the evaluation of progressive damage in concrete.
