ANALYTICAL AND EXPERIMENTAL INVESTIGATION OF STRESS DISTRIBUTIONS IN LONG FLAT PLATES SUBJECTED TO LONGITUDINAL LOADS AND TRANSVERSE TEMPERATURE GRADIENTS

摘要

Stress and strain distributions were studied in long flat plates in order to develop practical analytical procedures for the design analysis of aircraft structures at elevated temperatures.nMethods of analysis for calculation of stress distributions under various load-temperature conditions are presented. These include:n(1) Thermal stress distributions in the elastic and plastic range;n(2) Combined load and thermal stress distribution in both the elastic and plastic range;n(3) Load induced compression-buckling stresses at elevated temperature.
