Abstract:
In this paper, wave propagation in concrete with inhomogeneity is examined using numerical simulations. Simulated damage is filmshaped to resemble the actual shape of cracks. Results of pulse velocity and wave distortion are compared with experimental ones, showing good agreement. It is concluded that, apart from the volume content, the characteristic shape and orientation of damage are crucial for wave propagation influencing the correlations between velocity and damage.
