Characterisation of local homogenized complex young’s modules of curved beam in composite material by using an inverse method and a finite element operator

Résumé

Identification of elastic and damping properties is a challenge for fabrication of composite materials , which can have complex shapes. A new approach based on the Force Analysis Technique (FAT) was developed to identify structural parameters from local equation of motion. For structures with known analytical models, this method worked well. This work presents a similar approach to extend the previous method to the structure which can be described with known analytical models. This knowledge of the model is replaced by a finite Element (FE) operator. In this paper, identification of complex Young's Modulus from measured displacement fields is shown using the FE model. To denoising the measured displacement a procedure based on a probabilistic approach coupled to a residue minimization is proposed. The method is illustrated on a curved beam using simulated displacement.
