Abstract

Buckling analysis was carried out for relatively thick cylindrical shell with axial crack subjected to axial compression using the experimental and numerical approach. Presence of crack can considerably reduce the buckling load of a shell structure. Thus, the effect of the crack size on the buckling behavior was studied. This experimental and numerical analysis work been conducted with eight mild steel cylinders with the inner diameter-to-thickness ratio, D/t≈ 50, diameter to axial length ratio, D/L≈0.89. The experimental results show that as axial crack length increases, the buckling load carrying capacity of the cylindrical shell decreases. It also shows the strength of cylindrical shell decreases with the crack length of five percent and ten percent. Finally, the results of buckling behavior of the relatively thick cylindrical structure depends on the crack length, is discussed.
