Understanding and modeling the fracture mechanical behavior of short glass fiber reinforced polymers (SFRPs) is challenging since the strong heterogeneity induced by the manufacturing process causes a tight coupling of the material’s microstructure to the effective response on the component scale. Aiming to account for this microstructural complexity, fracture is approached using a multiscale approach. Typically manufactured via injection moulding, SFRP components exhibit locally varying microstructural configurations posing the main challenges of anisotropy and heterogeneity to fracture mechanical approaches. To resolve microstructure induced anisotropy, established isotropic phase field models of brittle fracture [1] are extended towards the anisotropic case. Besides an orthotropic ground state elasticity and a first order anisotropic crack surface density function, we propopse, inspired by [2], a multi-degradation mechanism for the anisotropic degradation of the orthotropic stiffness. For tackling the heterogeneity in a macroscopic component, a microstructure interpolation concept is introduced and implemented into the commercial software package Abaqus with a pre-trained material database at its core. To create the database, the anisotropic elastic coefficients are obtained from previously executed micromechanical simulations on realistic microstructures using the efficient microscopic solver FeelMath. High-precision component scale fracture mechanical simulations in Abaqus require knowledge of the local microstructural configuration which we obtain from injection molding process simulations using Moldflow and subsequent mapping onto the structural domain. Basic characteristics of the anisotropic multi-degradation mechanism model are discussed based on analytical and numerical benchmark tests. Finally, component-scale simulations with increased complexity are shown to demonstrate the application of the proposed simulation method in an industrial context.
