Plastic buckling of dented steel circular tubes under axial compression: an experimental study
journal contribution
posted on 2023-05-18, 08:32 authored by Ghanbari Ghazijahani, T, Jiao, H, Damien HollowayDamien HollowayThis paper examines the effect of large local imperfections, known as dents, on the plastic buckling capacity of short steel tubes under axial compression. A total of 11 tests on such short columns were carried out. The specimens were indented through a separate process and the ultimate axial capacity was subsequently obtained through compression tests. Dent imperfections with various depths were introduced to different locations on the body of the specimens. Plastic buckling modes as well as the ultimate capacity of the specimens were thoroughly investigated. The adverse effect of such a local damage on the load carrying capacity was quantified for different values and types of imperfections.
