Pagination or Media Count:
Torsional buckling strength for thin walled monocoque cylinders of varying skin gages at a temperature of 260 F was determined. The effect of a heat rise rate of 6 Fsec. on the test specimens was required. Strain gage and tensile coupon data are presented. Heat rise rates up to 10.3 Fsec were measured with no detrimental effect on test specimens. All test specimens failed by shear buckling with 45 degree shear wrinkles developing in the skin over the 20 inch bay. Author
