This paper focuses on pattern recognition of the best position of piezoelectric patches
around the hole in a plate under tension to attain the maximum reduction in stress
concentration factor. For this purpose, using particle swarm optimization algorithm, the area
and the best location of piezoelectric patches are investigated and the optimum pattern
recognition around the hole is presented. Then, the effect of increasing the area of

This paper focuses on pattern recognition of the best position of piezoelectric patches around the hole in a plate under tension to attain the maximum reduction in stress concentration factor. For this purpose, using particle swarm optimization algorithm, the area and the best location of piezoelectric patches are investigated and the optimum pattern recognition around the hole is presented. Then, the effect of increasing the area of piezoelectric patches and voltage on stress concentration reduction are investigated for all percentage area of piezoelectric patches. To confirm the results, by considering two experimental tests, the results are compared with those reported in presented paper.
