Identification of tensile damage in concrete by Acoustic Emission

Đang chuẩn bị nút TẢI XUỐNG, xin hãy chờ

In this paper, aiming to improve this classification technique, authors have performed tensile test on concrete specimen in order to determine the signal parameters as well as waveforms and to assess the influence of material to wave propagation. After filtering the raw data, the usual RA-AF classification process is used to determine the proportion of each type of damage (Mode I and Mode II). | Identification of tensile damage in concrete by Acoustic Emission
