Аннотация:An approach for studying the critical loading parameters of stability of an elastic plate with nonlinear supporting elements is developed. A general potential function of the system depending on state variables and control parameters is constructed. Classical methods of catastrophe theory including a determination of the different bifurcational sets and an analysis of the physical meaning of the corresponding stability criteria are used. The influence of the supporting elements on the behavior of the plate under the loading is determined
