STRESSES IN MARINE PROPELLERS

A rational approach to the general solution of the propeller strength problem is established. A finite-element displacement model is utilized to predict the behavior of an elastic body having an arbitrary shape and subjected to prescribed loading. Solid elements in their general form are adopted. This formulation bypasses the constraints of simplified assumptions commonly employed by many classical plate and shell theories, and allows a more realistic approximation to the true structural configuration than is possible by most other conventional approaches. The application of the present procedure is simple and straight-forward. Good agreements with measured displacements and experimental stress data were obtained for a highly skewed blade as well as a supercavitating blade.
