Influence of Shear Deformation of the Cross Section on Torsional Frequencies of Box Beams

One of 4,119 reports in the series: NACA Technical Notes available on this site.

Description

"An exact analysis has been carried out on the torsional vibrations of a four-flange box beam with cross sections which can change shape because the stiffness of the bulkheads is finite. The effect of shear deformation of the cross section on the torsional frequencies is illustrated by numerical calculations. An approximate method for quickly estimating the effects of bulkhead shear stiffness on the torsional frequencies of box beams has been devised" (p. 1).

National Advisory Committee for Aeronautics Collection

The National Advisory Committee for Aeronautics (NACA) was a U.S. federal agency founded on March 3, 1915 to undertake, promote, and institutionalize aeronautical research. On October 1, 1958 the agency was dissolved, and its assets and personnel transferred to the newly created National Aeronautics and Space Administration (NASA).
