Finite Element Analysis of Plastic Cups
In the past, many research about forming of plastic sheets, especially thermoforming, have been carried out to
predict wall thickness of containers and effects of forming parameters to the thickness distribution. In contrast, this paper
demonstrates the use of finite elements to improve material usage in manufacturing process. By varying thickness and
applied loads in the simulation, stiffness of a cup can then be compared and used to choose the proper value of the wall
thickness that meet the actual requirements. Results also display that the increasing rate of the stiffness will reduce as a
