“…Although the Finite Element Method (FEM) is the most widespread by researchers [ 8 , 10 , 11 , 12 , 13 ], it is hard to apply with predictive models. The Upper Bound Method (UBM) is a known methodology that accurately models real processes, and is preferred by some researchers [ 3 , 4 , 14 ].…”

Metal containers (both food and beverage cans) are made from huge steel or aluminum coils that are transformed into two- or three-piece products. During the manufacturing process, the metal is sprayed on both sides and the aerosol acts as insulation, but unfortunately produces volatile organic compounds (VOCs). The present work presents a different way to manufacture these containers using a novel prelaminated two-layer polymer steel. It was experimentally possible to verify that the material survives all the involved manufacturing processes. Thus tests were carried out in an ironing simulator to measure roughness, friction coefficient and surface quality. In addition, two theoretical ironing models were developed: upper bound model and artificial neural network. These models are useful for packaging designers and manufacturers.

Metal containers are the most commonly used packaging worldwide in both the food processing industry. Usually, the production processes involved in the canning industry include multi-step transformations that take large aluminum or steel coils and make them into two or three-piece cans. During this process, these parts are sprayed to obtain a better surface for the contents; however, this spray produces volatile organic compounds (VOC). This paper presents a new and environmentally friendly can manufacturing method, which uses a novel pre-laminated two-layer polymer steel. As experimentally proven, this innovative polymer-coated steel successfully withstands every manufacturing requirement. The specimens were tested in an ironing simulator, measuring roughness, and friction coefficients. The development of an upper bound ironing model, along with a supporting neural network, allows an insight into the design of new materials for can manufacturing.

Upper-Bound modelization of an ironed three-layered polymer coated steel stripAbstract Global beverage can and food container consumption is very high, with billions of cans produced annually worldwide. There are several steps in can manufacturing, but ironing is the most crucial. In a previous work [1], a series of ironing experiments were reported using a new material and an ironing simulator. This material was a three-layered polymer coated steel, and it was seen that under some process conditions, it survived the ironing process with no damage in any of the three layers. The critical die angle was determined as well as specimen quality surface tests.In this paper, an associated theoretical ironing model is described, using the Upper Bound Theorem, and considering the cases of successful ironing or shaving. It's possible to give insight into how to design a material that irons well. For example, the optimal layer thicknesses are also found.
