RÉSUMÉ

A method for the solution to the flexural center problem of prismatic bars composed of different materials by means of hydrodynamic analogy is developed. The problem is reduced to evaluation of the strength of the sources and vortices on the outer contour of the bar and along the boundaries separating different materials. The results of numerical implementation are provided.
