Validation in hybrid experimental-numerical vibration analysis

Abstract

The problem of plate bending using reflection moire is analysed in this paper. Nonlinear mapping of relative error norms of finite elements is used for better utilisation of the intensity scale. The relative error norms for the eigenmodes of the plate simultaneously showing the shape of the reflected plate deflected according to the corresponding eigenmode are obtained. The method for the validation of digital fluid holographic images based on the relative error norms represented by intensity mapping for the structure deflected according to the eigenmode is presented.
