A thermo-coupled constitutive model for semi-crystalline polymers at finite strains: Application across scales
Abstract: Fiber reinforced thermoplastics are widely used for thermoforming and injection moulding processes, since their high strength to mass ratio is favorable for various industrial applications such as, for example, automotive engineering. Semi-crystalline polymers, as the composites matrix material, make up a subcategory of thermoplastics, which partly crystallize after cool-down from the molten state. They are reinforced with glass or carbon fibers to enhance their material performance. Nevertheless, during the thermoforming process, unwanted residual stresses can arise, due to the complex material behavior of semi-crystalline polymers under different temperatures and strain rates. The interaction between matrix and reinforcement being another unknown factor. Therefore, computational models are needed to predict the material response reliably and minimize production errors. This work presents a thermomechanically consistent phenomenological material formulation for thermoplastics at f.... https://journals.ub.ovgu.de/index.php/techmech/article/view/2138
