The researchers whose trusted networks rank it highest, strongest advocate first. Every researcher gets a different order.

Revisiting the problem of a crack impinging on an interface: A modeling framework for the interaction between the phase field approach for brittle fracture and the interface cohesive zone model (2017, result): “With reference to the phase field approach, following [87,88], the regularizing parameter l can be interpreted as characteristic fracture-length scale of the bulk, which influences the apparent failure stress σPF of the system.”
Crack nucleation in variational phase-field models of brittle fracture (2018, unknown): “However, the few studies providing experimental veriﬁcations [81, 75, 22] are still insuﬃcient to fully support this conjecture.”
Initiation and propagation of complex 3D networks of cracks in heterogeneous quasi-brittle materials: Direct comparison between in situ testing-microCT experiments and phase field simulations (2016, methodology): “Finally, Nguyen et al. (2016a) performed direct quantitative predictions of crack propagation in drilled plaster specimen under compression with phase field numerical simulations which favourably compared with experimental investigations obtained in Romani et al. (2015).”
Multi-phase-field modeling of anisotropic crack propagation for polycrystalline materials (2017, unknown): “Such analysis has been conducted with experimental validations in [37,38].”
