Abstract
At Tetra Pak, general knowledge of food and beverage processing is of great importance. This in turn, depends on the equipment used for the particular process. One of these equipment consists of deformed tubes made of stainless steel 316L. The aim of the present work is to get an understanding of the material 316L. To achieve this, physical tensile tests are performed to study the material behaviour under quasistatic and dynamic loading conditions. Virtual tensile tests are created where the material behaviour is described with existing material models in Abaqus/Explicit. The proposed material models are Bilinear, Multilinear and Johnson-Cook isotropic hardening models. A material model is today used to describe the material behaviour and... (More)
At Tetra Pak, general knowledge of food and beverage processing is of great importance. This in turn, depends on the equipment used for the particular process. One of these equipment consists of deformed tubes made of stainless steel 316L. The aim of the present work is to get an understanding of the material 316L. To achieve this, physical tensile tests are performed to study the material behaviour under quasistatic and dynamic loading conditions. Virtual tensile tests are created where the material behaviour is described with existing material models in Abaqus/Explicit. The proposed material models are Bilinear, Multilinear and Johnson-Cook isotropic hardening models. A material model is today used to describe the material behaviour and is compared with the proposed material models.

For quasistatic cases, the findings in virtual tensile tests compared to experimental data are: the multilinear and the Johnson-Cook models give a good prediction of plastic behaviour, whereas the bilinear model gives a rough estimation of plastic deformation. In addition, use of the proposed material models result in a stiffer response of the material in comparison with the currently used material model. For dynamic cases, effects of strain-rates on material properties are investigated using isotropic hardening combined with rate-dependent models such as Cowper-Symonds and Johnson-Cook in Abaqus/Explicit. It is found that there are different approaches to determine the parameters in these material models, making it hard to verify the accuracy. In spite of the fact, the results from the study indicate that the material is rate-dependent. Therefore, a rate-dependent material model is necessary to capture the material behaviour. (Less)
Popular Abstract
What does it take to form a material such as steel? How does it behave during forming? If you have the knowledge of it. How can you describe this behaviour virtually to be as close as the real world application? In this thesis we answer these questions when we investigate the material behaviour of one specific steel that is often used in food and beverage processing industries.
