Abstract: The finite element approach for strength analysis of marine propeller blades is used to a growing extent. For the time being it is the proper method to be employed in order to obtain detailed and reliable information about the stress distribution over a propeller blade. The underlying article describes the application of a rather simple solid element type for static blade stress calculations. A solid element was preferred to plate or shell elements, because of the three-dimensional nature of the blade region near the hub. On the other hand it facilitates an extension of the considered structure into the hub. Results of these calculations are presented in comparison with values obtained by means of strain gauge measurements on a separate full scale blade.
