The computer program now has the capability of utilizing 108 degrees of freedom in the process of generating stress distributions for propeller blades. The results of such a test run have been plotted and may be compared with similar plots of results which were generated using 84 degrees of freedom. These comparisons indicate that no radical change in stress contours occurs as a result of increasing the number of degrees of freedom from 84 to 108 indeed, there is a marked similarity between the two sets of plots. This similarity indicates that the solution has settled down and that 108 degrees of freedom are adequate for the purpose of depicting the variation of displacement components over the planform of propeller blades. Thus, increased confidence is warranted in the capability of the subject computer program to generate accurate stress distributions for static, distributed loadings on propeller blades.
