In this webinar, a procedure for the prediction of the vibration behavior of short fiber reinforced structural components considering the anisotropic material properties is presented. The fiber orientation is determined by an injection molding simulation and transferred to the structural mechanics model. The determination of the anisotropic stiffness characteristics of the composite material is based on a multiscale material model. The identification of the parameters of the material model is carried out by comparison with resonance measurements on simple bending bars. As an example, results for an engine bracket are presented. Due to the comparatively simple application and scalability of the procedure, high-performance computations can also be conducted for large models.
