LARGE DEFLECTIONS OF CLAMPED RECTANGULAR PLATES.

Abstract

An approximate solution is given for large deflections of a clamped-edge rectangular plate under the combined action of edge thrust (or thermal strain) and lateral load. To determine center deflection and stresses, a one-term approximation to the lateral deflection mode is used in a modified energy method. The effects of nonrigid supports are examined for the case of zero lateral pressure, and it is found that while elongation of the supports is accountable by simple modification of edge thrust terms, support bending requires more substantial revision of the analysis. The concept of thermal load is introduced and calculation methods are provided for uniform and non-uniform temperature distribution in the plane of the plate. To establish the region of applicability of the analysis, critical loads are computed for more complex panel buckling modes. (Author)
