Question
Transcribed Image Text: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
