Abstract
In an earlier paper (1) an analysis was carried out to determine the stresses and deflection in an infinite strip plate undergoing large deflections when the plate was subjected to a combined normal loading and uniform temperature rise through the thickness, both of which were permitted to vary across the plate width. This paper extends the analysis and design charts to the case where the temperature distribution through the thickness of the plate may have any desired distribution. If the usual plate assumptions regarding plane sections remaining plane are valid, then the arbitrary temperature distribution can be represented completely by the average temperature and the first moment of the temperature about the plate middle surface, as far as the engineering stresses and deflections are concerned. The convenient nondimensional design charts cover equilibrium positions in the buckling as well as nonbuckling range and show maximum stress and central deflection as a function of pressure, average temperature, and temperature moment for cases of both clamped and simply supported edges.
