THERMAL STRESSES AND THERMAL BUCKLING

摘要

Methods available for the analysis of thermal stresses in flat plates of rectangular plan form and of constant or variable thickness are derived, discussed, and generalized to be valid in the case of a variable thickness. Recommendations are made for the practical calculation of the thermal stresses, An experimental verification of the thermal buckling theory of the coverplates of multicellular supersonic wing structures is presented. The experiments were carried out with the aid of the electromagnetic induction heater developed at the Polytechnic Institute of Brooklyn. The experimental results obtained agree well with the predictions of the theory.
