ADVANCED MULTIFIELD MODELS FOR WAVES PROPAGATION ANALYSIS IN METALLIC PANELS

Résumé

Active health monitoring of structures throughout their life cycle is a privilege in the different industrial domains. However, it is essential to the domains where the structures are made of composite materials due to the complex damage mechanisms involved compared to metals [1] and due to the absence of an accurate numerical model that permits the prediction of their failure. In this work, the assessment of a multifield layer-wise finite element dynamic plate model (MUL2) based on the Carrera Unified Formulation (CUF) is conducted, on an isotropic aluminum material strip, in order to verify the validity of the model and to finely tune the parameters needed to accurately model wave propagation in the future in laminated material of orthotropic nature. The convergence of the plate model was studied under different modeling parameters, including mesh density, to-the-thickness kinematic model, plate element type and the number of timesteps.
