THERMAL BUCKLING OF CENTRALLY HEATED CIRCULAR PLATES

Abstract

The behavior of a centrally heated flat circular plate with axisymmetric temperature distribution and free edge conditions is investigated theoretically and checked experimentally. Thermal stresses occur when the temperature is not unifor and cause buckling if t e temperature rise is sufficiently large. The buckling mode isAXISYMMETRIC. Large deflections are obtained for temperatures above the critical value. Theoretical calculations include solutions of the buckling problem as well as the post-buckling behavior of the plate. Attempts are made to introduce the effect of initial irregularities in the plate and to solve the large deflection problem. Experimental ata give temperature distributions and deflected hapes. The results btained from the theory are checked with a satisfactory degree of accuracy. (Author)
