| Περίληψη | The reflection of elastic waves from subsurface interlayer unilateral cracks, with the possibility of crack closing (contact) and frictional effects, is studied by dynamic boundary element method (BEM) combined with a linear complementarity problem (LCP) formulation. The effect of the unilateral crack on the impact–echo response is studied by means of numerical experiments. Further, a neural network model is proposed and tested for the classification of the data based on the numerically generated waveforms. The position or the size of the sublayer crack can be identified from the trained neural network. | en |
