Panels under Thermal Stress: The Behaviour of a Panel Restrained against Expansion in one Direction and Loaded in the other Direction when Subjected to Kinetic Heating

This paper discusses the problem of a panel attached along two of its edges to heavy members which respond only slowly to external temperature change and thereby prevent its free (hernial expansion, and along the other two edges, parallel to the direction of loading, to light members which permit free expansion. It is shown that the load‐bearing capacity of such a panel is generally small, if buckling is to be avoided, but that much greater loads can be carried in the post‐buckling condition, provided that a small degree of rippling can be tolerated. The paper includes a number of numerical examples, in one of which the concept of a load‐temperature envelope is introduced.
