Buckling Behaviour of Dented Aluminium Alloy Cylindrical Shell Subjected to Uniform Axial Compression
Apstrakt
Thin-walled cylindrical shells are widely used in aerospace and automotive industries and in civil engineering. Usually their function is to transmit the axial loading – to be under pressure. When the pressure reaches a critical value, it comes to the buckling of the walls. Furthermore, due to small thickness of walls, there may be local imperfections, which further reduce the value of critical buckling stress. The imperfections present in thin cylinders are classified as geometrical imperfections, material imperfections and other imperfections. The imperfections such as circularity, cylindricity, local indentations, dents, crack, swellings, non-uniform thicknesses, etc., belong to geometrical imperfections whereas imperfections such as in-homogeneity, vacancies, impurities, etc., are classified as material imperfections. The residual stresses and strains induced during manufacturing, etc. are grouped as other imperfections[1].
Aim of this paper is to investigate how geometrical impe...rfections such as dents, positioned in the middle of aluminium-alloy cylindrical shell, have influence to critical buckling stress.
