Patch loading - analytical approach to critical load determination

Abstract

The problem of plate stability under patch-loading can be analyzed using a variety of mathematical models by which the problem can be more or less realistically described. Models adopted in this paper serve as the basis for checking applicability of the analytical solution when subjected to complex load conditions. The accuracy of the procedure, proven by comparison with the data obtained through numerical models, and achieved by introduction of the exact stress function and use of appropriate deflection functions, confirms correctness of the solution presented in the paper.
