| Summary: | The rapid development of smart and intelligent
structure has led to the application of piezoelectric patches in
repairing techniques. The advantage of using piezoelectric patch
is that its behavior can be controlled by considering its
electromechanical properties. The piezoelectric patch that can be
used for sensing and actuation make it suitable to be used in
active repair. In this paper, an experimental approach of active
repair on an edge crack specimen using two piezoelectric patches
was carried out. To observe the effect of the active repair, the
stress intensity factor (SIF) was measured using strain data that
was obtained from the strain gages located near to the crack tip.
The edge crack specimen was put under Mode 1 loading
condition as the active repair using piezoelectric patches was
applied. The results showed reduction of SIF from the effect of
the active repair. |
