Abstract

This communication presents a numerical computation strategy for the modelling of the ultrasonic inspections of CFRP composite structures based on a specific use of high order spectral finite elements. The overall computation performance is enhanced by considering a block-structured domain decomposition approach. This decomposition incorporates within the finite element computations relevant physical information, such as the representation of the specimen prior to and after its potential deformations, leading to an efficient reconstruction of local fiber orientations. The numerical solver is embedded within the CIVA simulation platform, and we propose several numerical illustrations of relevant 2D configurations of curved CFRP composites including potential flaws such as ply waviness.
