Unformatted text preview: xx ( y ) , at the point of buckling. 1 Problem 2 A long cylindrical shell made of mild steel ( E = 210 GP a and = 0 . 3 ) is sti f ened in x-direction by a system of eight equally spaced stringers. This shell is subjected to axial compression. 1 mm l = 2 m 0.1 m h = a = (a) Determine the buckling mode of the shell, ( m, n ) . (b) Calculate the corresponding half-wave length, . (c) Determine the theoretical buckling stress, cr 2...
