Figures & data
Figure 1. Far-field US scanning of the unknown crack under reconstruction.
Figure 2. An elementary crack in the elastic medium.
Figure 3. Mutual influence of i-th and j-th elementary cracks.
Figure 4. Reconstruction of a semi-circle crack, exact input data: solid line – true boundary contour; dashed line – reconstructed boundary.
Figure 5. Reconstruction of a self-intersecting crack, 5% relative error in the input data: solid line – true boundary contour; dashed line – reconstructed boundary.
Figure 6. Reconstruction of a complex-shaped crack, 10% relative error in the input data: solid line – true boundary contour; dashed line – reconstructed boundary.
