Buckling of Axially Compressed Conical Shells with Multiple Imperfections

Abstract The influence of single and multiple imperfection cases on the load carrying capacity mild steel cone subjected to axial compression was considered through numerical simulation in current paper. Three different techniques were considered, which are: i) uneven length (sinusoidal/square waves), ii) crack, iii) indentation (SLI) imperfection. Abaqus 6.19 FE used carry out simulation. compressive applied at small radius cone. Results showed that buckling axially compressed depends approach implemented. cones seen be heavily affected by for both Also, effect is more noticeable higher r1/t.
