title = "CHARACTERISTIC LENGTH-INSENSITIVE PHASE-FIELD DAMAGE MODELING OF CRACKS IN FIBER-REINFORCED COMPOSITES WITH FFT SOLVER",
abstract = "Using an FFT-based solver for phase-field modeling of damage is attractive because it can enable massive parallelization. Before applying it for complex analysis, the characteristic length, an important parameter of phase-field damage models, needs a prudent discussion. This parameter is commonly treated as a material parameter since it can hugely affect the predicted mechanical behavior. However, for heterogeneous materials, our recent studies have shown that the choice of the characteristic length affects not only the macroscopic mechanical behavior but also the local crack patterns. This makes it difficult to get proper macro-responses and local crack patterns simultaneously. Consequently, this work addresses the implementation of a lengthinsensitive phase-field model with an FFT solver to deal with the above issue. Meanwhile, a criterion for choosing a proper characteristic length for this phase-field model is also proposed in this work.",
