      Hi everyone,nI have a stator segment including winding and due to adding epoxy resin, it is difficult to understand the dynamic behavior of the segment. I have the results of natural frequency and mode shapes of the vibration experiment (Experimental Modal Analysis-EMA) and, I want to know if it is possible to use a genetic algorithm to match the FE results to experimental results and find anisotropic properties ( different direction has different elastic properties). so basically by means of genetic algorithm, I want to find Young's model, shear module and poisson's ratio ( 9 in total X,Y,Z direction) in each direction to have minimum residual of natural frequency between ANSYS result and Experiment.nThank You so much in advancennBest Regards,nOmid.n

      ,nYou could refer the methodology followed in this article https://www.hindawi.com/journals/sv/2019/9029026/. This is another article which uses a simpler approach https://www.sid.ir/FileServer/JE/81320050105.pdfnRegards,nIshan.n
