[Structural Analysis Example] Buckling Analysis of an Empty Can

The initial buckling location is in the body due to the increase in strength at the bottom! Here is an analysis case using "Ansys LS-DYNA."

We will introduce an analysis example that evaluates the buckling load and buckling shape of an empty can compressed in the vertical direction. In buckling analysis, even slight errors in the initial shape can lead to buckling behavior. Even if the analysis data has the same plate thickness, basic shape, and material properties, considering initial imperfections causes the initial buckling location to change from the bottom to the body. Additionally, when considering work hardening at the bottom of the empty can, the strength of the bottom increases, resulting in the initial buckling location being at the body. In the related links below, we present the analysis results in a video, so please take a look. [Summary] - Even if the analysis data has the same plate thickness, basic shape, and material properties, considering initial imperfections causes the initial buckling location to change from the bottom to the body. - When considering work hardening at the bottom of the empty can, the strength of the bottom increases, resulting in the initial buckling location being at the body. *For more details, please refer to the related links or feel free to contact us.
