Non-destructive testing is used in monitoring health of structures. In this paper, nonlinear ultrasonic test was done to analyze the sensitivity of the fundamental and higher harmonics with the internal damage in concrete. Good sensitivity produces significant quantitative changes in the nonlinear s...
