Abstract (English):
The stability problem of rectangular in plane shallow cylindrical panel under the transverse force applied at the center of the panel was solved using the finite difference method and the theory of shallow elastic shells. The curvilinear edges of the panel are based freely on the hemispherical supports. Under the static loading the panel is deformed with the formation of a large deflections. The panel is a primary element of pushbutton switch for which the magnitudes of the upper and lower critical forces are determined.
