Abstract: Plotting of moire fringes from the results of finite element calculations is important because of the ability of direct comparisons with the experimental results of analysis. The smooth variation of the intensity of the lines on the surface of the structure according to the trigonometric law is proposed. The method is applied to the visualisation of the inplane vibrations by stroboscopic photographing of the structure in the state of equilibrium and in the state of extreme deflections. Finally, the method is modified for the analysis of circular structures producing digital angular and radial moire fringes
