Abstract
The buckling of imperfect shells is the most challenging problem in industry and an understanding of the buckling load of shells structure is needed to assure the integrity of these shells during their service life. To get a better understanding on this problem, a study was conducted to examine the buckling load of axially compressed cone with crack that have different orientation and length. 1-mm mild steel was chosen in this study. A mild steel plate has been cut using Waterjet machine and rolled using rolling machine in a form of 21 conical shells. There are three types of crack introduced to the cones which are axial, circumferential and angled crack. Every type of crack has six different length which are 5%, 10%, 15%, 20%, 25% and 50% of the cone circumference. Three of the 21 specimens have no crack. All the specimens were axially compressed using 150 kN Instron Machine to determine the buckling load. From the results obtain, it was found that the 5% crack length produced highest buckling load for every crack and the lowest buckling load is at 50% crack. Every type of crack was compared at 50% of crack length, and it was found that, the axial crack has highest buckling load which is 35.73 kN follow by angled crack and circumferential crack which are 31.38 kN and 21.02 kN respectively. Hence, it can be concluded that, if the length of the crack is increase, then the buckling load is decrease. Again, it can also be concluded that, axial crack has the highest buckling load compare to circumferential crack that has the lowest buckling load.
