Abstract: A damage tolerance concept is an important prerequisite for improving the performance and service life-time of adaptive structures. In conjunction with experimental and numerical tools of electromechanical damage mechanics, high-resolution NDE methods are needed to detect manufacturing defects and to monitor the damage evaluation in a self-diagnostic manner. Mechanical tests combined with non-destructive on-line investigations are used to evaluate the early stage of damaging in CFRP specimens with embedded piezoelectric patches.

Keywords: adaptive structures; CFRP; damage tolerance; health monitoring; nondestructive evaluation; NDE; self-diagnostics; piezoceramics; smart materials; carbon fibre reinforced plastics.
