National Advisory Committee for Aeronautics, Technical Notes - Strength Tests of Thin Walled Duralumin Cylinders of Elliptic Section
This report is the fifth of a series presenting the
results of strength tests of thin—walled cylinders and
truncated cones of circular and elliptic section; it in;
cludcs the results obtained frOm torsion tests on 30 ayIZ‘
inders, pure bending tests on 30 cylinders, and combined
transverse shear and bending tests on 60 cylinders. All
the cylinders tested were of elliptic section with the
ends clamped to rigid bulkheads. In the pure bending and
combined transverse shear and bending tests the leads were'
applied in the plane of the major axis.
The results of the tests on elliptic cylinders are
correlated with the results of corresponding tests on sir;
cular cylinders and are presented in charts suitable for
use in design.
As part of an investigation of the strength of
stressed~skin. or monoc0que, structures for aircraft. the—
Hational Advisory Committee for Aeronautics in caopsra; '
tion with the Army Air Corps; the Bureau of Aeronautics,
Navy Department; the National Bureau of Standards; and the
Bureau of Air Commerce has made an extensive series of
tests-on thinrwalled duralumin cylinders and truncated
cones of circular and elliptic section. In these tests.
the absolute and relative dimensions of the specimens were
varied to study the types of failure and to establish use—
ful quantitative data in the following loading conditions:
torsion, compression, bending. and combined loading.
