Abstract:
Metal drums are useful and adaptable medium-sized cylindrical containers, which can be used both for transporting liquids and semi-solids. Its circular shape provides maximum strength, allowing it to be tipped over and rolled even when fully loaded. Among the efforts aimed at sustainable measures are those aimed at geometric improvements for an optimized use of metallic sheets that are the input material in the manufacture of steel drums, with these generally manufactured from cold-rolled steel sheets with thickness ranging from 0.292 mm to 2.4 mm. Therefore, the present work aimed to analyze the effects of reducing the thickness of the metallic sheet used in the manufacture of 200L steel drums on the axial compression resistance resulting from stacking. For this, the finite element method was used to simulate the loading conditions for drums made from metallic sheets with thicknesses of 0.85 mm (original), 0.75 mm and 0.65 mm. The results obtained demonstrate that the maximum stress values undergo large variations when a thickness reduction is applied, keeping the same materials and the same boundary conditions, with the upper seaming region for thicknesses of 0.75 mm and 0.65 mm requiring special caution.
