    Buckling due to thermal stress of cylindrical shells subjected to axial temperature distributions
    (College of Aeronautics, 1961-05) Johns, D. J.; Houghton, D. S.; Webber, J. P. H.
    Thermal stress distributions in uniform circular cylindrical shells due to axial temperature distributions are investigated. The discontinuity effect due to the presence of a cooler stiffening bulkhead is considered, and the possibility of thermal buckling of the shell due to the circumferential discontinuity stress is examined. The buckling analysis is based on Donnell's shell equation, and particular attention is given to shells having clamped edges. An experimental investigation of this buckling problem is discussed, and the results obtained are seen to agree reasonably well with theory.

    Thermal buckling of a free circular plate
    (College of Aeronautics, 1960-08) Webber, J. P. H.
    The buckling of a free circular plate subjected to a temperature field, which varies only in the radial direction, is considered. The problem is first investigated experimentally and the mode of deflection and form of the temperature distribution are measured. Expressions are developed for the thermal stresses and the deflection mode of the plate, which are used for a theoretical small deflection energy analysis. This solution is found to compare favourably with the experimental results.
