Experimental Deflection Survey of Cantilever Sectors of Uniform Thickness


Garrett, Joseph (1949) Experimental Deflection Survey of Cantilever Sectors of Uniform Thickness. Engineer's thesis, California Institute of Technology. doi:10.7907/YP13-NN87.


The purpose of this investigation was to experimentally determine deflection data for 0 to 180 degree uniform thickness cantilever sectors. The basic deflection data is presented in the form of influence coefficients that can be utilized in the determination of the deflection of sectors as caused by any regular transverse loading. One phase of the investigation was specifically planned to achieve results that could be compared with an analytical solution of the problem. In addition to the basic experimentation, preliminary investigation was made of the effect of thickness and boundary fixity on the stiffness of cantilever sectors. Deflection modes as calculated from the data of this investigation were in close agreement with those determined by the analytical solution. Agreement in absolute magnitude was of the order of 15 percent for three loading conditions checked. Further investigation into the effect of thickness is considered desirable before the results of this investigation are applied to the determination of deflections for sectors of different thickness from those used in the investigation. The investigation was carried out in the Guggenheim Aeronautical Laboratory at the California Institute of Technology, Pasadena, California.
