ABSTRACT:
This study focuses on optimizing wall thickness in HDPE bottles by simulating top-load tests, one of the most critical performance criteria, using LS-DYNA. The objective is to reduce and lightweight the wall thickness while ensuring that the Equivalent Von-Mises stress values remain below the yield strength of HDPE. Additionally, the study examines how the deformation observed in HDPE bottles changes when compared between the original geometry and geometries with reduced wall thickness. This approach enables the modeling of lighter bottles using LS-DYNA while aiming to achieve a more optimal design. The insights gained from this research will provide a foundation for future studies to produce more efficient and lightweight bottles.
