Abstract

Abstract: Rubber‐toughened thermoplastic polymers such as PC/ABS blends exhibit a pronounced plastic dilatancy in their overall deformation behavior which results primarily from damage mechanisms in the ABS phase while PC behaves plastically incompressible, e.g. [1]. In this contribution, two commercial PC/ABS blends of different composition and morphology are approximated through appropriate unit cell models featuring the two constituents PC and ABS as distinct phases. Different visco‐plasticity models are utilized to capture the specific deformation behavior of each phase. Numerical studies of the unit cell models looking at the effect of the blend composition on the overall response are compared with experimental data. (© 2017 Wiley‐VCH Verlag GmbH & Co.
