Two regions of action are controlled by two differential equations of the fourth order which were solved in terms of the Bessel functions. The relations between the foundation modulus and the buckling load were found from two characteristic equations expressed in terms of Bessel functions.24 leavesapplication/pdfen-USIn CopyrightLD5655.V855 1959.L56Buckling (Mechanics)Plates, Iron and steelThesis
