| Popis: |
The application of guided waves for detection of partially debonded interfaces or zones of imperfect contact between sub-layers and defects near an edge (surface-breaking defect) in laminate thin-walled composite is considered here theoretically and experimentally. The effect of imperfect contact between sub-layers of a specimen on dispersion and amplitude properties of elastic edge and Lamb waves propagating in a laminated composite structure is analysed. Edge wave interaction with a surface-breaking defect at the edge of the plate has been experimentally and numerically investigated. It is demonstrated that the amplitudes of edge waves caused by reflection and scattering of guided waves are high enough to be employed in NDE and SHM. |
