Numerical Simulation of Wrinkling Behavior of Tinplate Based on Yoshida Buckling Test Model

Based on Yoshida buckling test (YBT) model, the wrinkling behavior of tinplate was simulated by ABAQUS software under no application and application of disturbing forces at different positions, and simulated results were verified by experiments. The strain combination of the center point of square sheet under different wrinkling heights was studied by increasing the clamping width gradually, and the wrinkle height evaluation diagram of the tinplate was drawn. The results show that the off-plane displacement distribution perpendicular to the stretching direction of the square sheet was almost the same under application of disturbing forces at different positions, indicating that the position of disturbing force hardly affected the wrinkling behavior. The simulated off-plane displacement distribution perpendicular to the stretching direction of the square sheet center section under application of disturbing force was in agreement with the experimental results, indicating that the simulation method of using disturbing force instead of actual influencing factor was accurate. The compression strain and tension strain of center point of square sheets with different clamping widths both increased with the increase of wrinkling height. Under the same wrinkling height, the compression strain and tension strain of center point of square sheets both increased with the increase of clamping width.
