STUDIES ON THERMAL STRESSES FUR AIRCRAFT STRUCTURES EXPOSED TO TRANSIENT EXTERNAL HEATING VOLUME II AN ANALYTICAL METUOD FOR THE P8E0ICTI0N OF THE BEHAVIOR OF A SHEET-STRINGER PANEL WITH A UNIFORMLY HEATED SURFACE

摘要

This report is a study of the behavior of a sheet-stringer panel with a uniformly heated surface. The panel is idealized such that the heat conduction analysis can be combined with the elastic heated plate equations enabling prediction of the transient stresses and deflections. The results show that a limiting load occurs which corresponds to the Euler elastic buckling criterion for slender columns. A method for predicting high temperature inelastic buckling is also suggested.
