| description | Active repairs using smart materials such as piezoelectric actuators can play a significant
role in reducing the crack damage propagation in engineering structures. This study analytically and
numerically investigated the active repair of center-cracked plates using piezoelectric actuators. First,
the stress intensity factor (SIF) for a center-cracked plate due to stress produced by a piezoelectric
actuator is analytically modeled. This analytical model is obtained by applying the method of weight
functions. In the second step, the solution is found for the center-cracked plate due to external
loading from known linear elastic fracture mechanics. These solutions are then superimposed, taking
into account the superposition principle to yield the total stress intensity factor for the integrated
piezoelectric actuator to the center-cracked plate. Finally, the proposed theoretical model is verified
by finite element simulation. The results indicated that the relative errors of the analytical model and
the FEA results are less than 5% in all the cases studied in this paper. |
