Abstract

The paper presents experimental studies on the buckling behaviour of axially compressed mild steel cones having crack imperfection. Three different crack orientations were considered, and they are: (i) circumferential crack (0°), (ii) angular crack (45°), and (iii) longitudinal (90°). Fifteen mild steel cones were fabricated with the following geometrical parameter: bottom radius-to-top radius ratio, r2/r1 = 2.0; top- radius-to-thickness ratio (denoted as cone thinness ratio), r1/t = 25; axial length-to-bottom radius ratio, L/r2 = 2.24; nominal shell thickness, t = 1 mm; cone angle, β = 12.6°. Experimental results show that increasing the crack length leads to a decrease in the collapse load of the conical shells. In addition, it can be seen from the test results that relatively thick conical shells are more sensitive to circumferential crack a compared to other crack orientation.
