抄録

This paper proposes an algorithm for multiple cracks reconstruction from ECT signals by means of a simulated annealing parallelized on a supercomputer. The algorithm takes not only the profiles of cracks but also the number of cracks as unknown, which is a very important feature from the practical point of view. A fast forward code using a database is upgraded for the rapid computation of the ECT signals of a differential mutual induction probe due to multiple cracks. The algorithm is applied to the reconstruction of the multiple cracks of a JSAEM round-robin test geometry. The reconstruction result using a simulated signal proves the validity of the proposed approach.
