摘要：
In this paper, a hybrid approach that combines both supervised (neural networks) and unsupervised (self-organizing algorithms) techniques is developed for damage identification in magnetoelectroelastic (MEE) materials containing cracks. A hypersingular boundary element (BEM) formulation is used to obtain the solution to the direct problem (elastic displacements, electric and magnetic potentials) and create the corresponding training sets. Furthermore, the noise sensitivity of the resulting approach is analyzed. Results show that the proposed tool can be successfully applied to identify the location, orientation and length of different crack configurations. (C) 2013 Elsevier Ltd. All rights reserved.
