Load-Bearing Capacity of Curvilinear Ice Plates Reinforced by a Rigid Insert

Keywords: ice plate, rigid-plastic model, curvilinear contour, rigid insert, incompressible foundation, ultimate load, material with different tensile and compressive ultimate stresses


A method is developed for determining the load-bearing capacity of ice plates, which are modeled by an ideal rigid-plastic plate located on an incompressible foundation. The plate with a simply supported or clamped arbitrary smooth curvilinear contour is subjected to a load uniformly distributed over an arbitrarily shaped reinforced local central region. An analytical expression for the ultimate load is derived. A plate shaped as an ellipse is considered as an example.
