This paper presents the results of the numerical analysis of thin-walled structures with a square cross-section. Aluminium models contain different types of triggers and distance to the base. Postbuckling analyses were compared with the form of the buckle to find the most beneficial location of the trigger. The study problem was approachedwith FEM Abaqus.Numerical analysis results are shown in theLoad–Shortening diagram. The data obtained during numerical analysis were used to determine the crushing efficiency indicators such as SE, CLE, TE. The aim of the research was to obtain the best efficiency indicators for the tested positions of triggers.
