This article focuses on how to simulate and predict the behaviour of plastic bottles under top load, squeeze load and crush load with SIMULIA Abaqus. We will explain the approach, the challenges and their solutions.
The geometry describes a PET bottle which can contain 0.5 l of drinkable liquid. Performing a top load analysis is important to determine the vertical stiffness of the bottle. This top load is also important to determine the vertical stack ability.
