摘要：

Design of NDT and NDE sensors is possible by solving Maxwell's relations with FEM or BIM. But the large number of geometrical and electrical parameters of sensor and tested material implies many results that don't give necessarily a well adapted sensor. The authors have used a genetic algorithm for automatic optimization. After having tested this algorithm with analytical solution of Maxwell's relations for cladding thickness measurement, the method has been implemented in Finite Element package and applied to the design of sensor for cracks detection under installed fasteners in aircraft structure.
