The transient elastic wave tests are conducted on the surface of the target structure. Then, either time domain or frequency domain signals are used to construct the image of the internal defect. The images can be used not only to determine the location of the internal defect but also the shape of the defect. Model tests and in-situ tests are presented to verify the effectiveness of these methods.application/pdf97474 bytesapplication/pdfzh-TW國立臺灣大學應用力學研究所混凝土裂縫缺陷彈性波影像法concretecrackdefectelastic wavesimagingreporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/21633/1/902211E002079.pdf
