| Abstract: | In order to find the relationships between the distortion rule of the concrete and its surrounding stress field, a real-time optical holographic setup is used to record the distribution and the variation of the samples, the waveforms of ultrasonic emission stimulated by the micro-cracks are recorded by a transient automatic waveform recorder to determine the time, location and intensity of the actions of micro-cracks. The experiment results are worthy studying. This method provides a useful experimental approach to study the brittleness materials. |
