Abstract
In this work, the challenges in forming of glass-fibre reinforced PA6, from experimental material characterization and parameter identification to numerical modelling using Finite Element Analyses (FEA) is reviewed and results are presented. Mechanical in-plane behaviour is characterized by tensile and bias extension tests. Out-of-plane characteristics are determined using the cantilever test. The constitutive model is set-up using LS-DYNA™, in which the fibre and matrix properties are considered separately. Therefore seperate tensile experiments with unreinforced PA6 are performed. FEA is used to model the tensile and cantilever tests in which the strain-stress curves, influence of displacement on shearing angle and different approaches in modelling the bending stiffness are compared. The advantages and drawbacks of the model are shown and discussed. It is shown that the conducted experiments can be reproduced by using the implemented material model and reasonably good results are achieved.
