On the basis of the results found, we were able to explain the mode conversion phenomenon related to the asymmetric position of the defect and we were able to determine the nature of the modes of the reflected and transmitted wave packets. The technique based on the summation and subtraction of the signals obtained by the transducers positioned at two identical positions with respect to the wave propagation axis has been developed to determine the nature of the reflected and transmitted modes when we have a mode conversion phenomenon. The influence of the defect dimensions on the reflection and transmission energy coefficients is studied. An energy quantification of the incident, reflected and transmitted modes is presented. The numerical control process using transducers is explained. The material considered is a thermo-plastic composite reinforced with carbon fibers. In this paper, we present a finite element numerical model of the interaction of ultrasonic guided waves with an internal defect from the fused filament additive manufacturing process.
