Question
A steel panel is subjected to a compressive loading in order to improve the panel stiffness and to increase its buckling strength. It is swaged with the swage depth of 13 mm and swage angle of 60.07°. Its profile is as shown in Fig.Q2. Typical dimensions are shown in the figure and the thickness of the panel is 0.8 mm. The effective length of the panel is 750 mm. The relevant properties are: Modulus of elasticity Yield stress 200 GN/m? 240 MN/m? . Assuming that the buckling stress coefficient for a panel simply supported on both sides is 3.62 and that the post buckling relationship for the panel is Oy = 0.40, +0.60, where oav = average panel stress, o, = edge stress in panel and o = panel buckling stress, determine (a) the load/swage pitch at which initial buckling of the panel will ccur, (b) the instability load per swage pitch. (13 Discuss the effects upon the compressive strength of the panel of: (c) i) Varying the swage width; ii) Varying the swage depth 150 13 150 All dimensions in mm Fig.Q2 Page 2 of 3 2.
