Journal ArticleDOI
A phase-field method for computational modeling of interfacial damage interacting with crack propagation in realistic microstructures obtained by microtomography
TL;DR: In this paper, a smoothed displacement jump approximation is introduced by means of level-set functions to overcome the issue of pixelized interfaces in voxel-based models, which allows interaction between bulk and interface cracks, and for arbitrary geometries and interactions between cracks.
Journal ArticleDOI
A phase field method to simulate crack nucleation and propagation in strongly heterogeneous materials from direct imaging of their microstructure
TL;DR: In this article, a shift strain split operator algorithm is proposed to handle unilateral contact within cracks in a very efficient manner by means of the phase field method for voxel-based models.
Journal ArticleDOI
Multi-phase-field modeling of anisotropic crack propagation for polycrystalline materials
TL;DR: In this paper, a new multi-phase field method is developed for modeling the fracture of polycrystals at the mi-crostructural level, where inter and transgranular cracking, as well as anisotropic effects of both elasticity and preferential cleavage directions within each randomly oriented crystal are taken into account.
Journal ArticleDOI
On the choice of parameters in the phase field method for simulating crack initiation with experimental validation
Thanh Tung Nguyen,Julien Yvonnet,Michel Bornert,Camille Chateau,Karam Sab,R. Romani,B. Le Roy +6 more
TL;DR: In this paper, the phase field method is used to study the initiation and propagation of complex crack networks without dependence to the finite element mesh. But the authors do not discuss the influence of parameters in the method and provide experimental validations of crack initiation in plaster specimens.
Journal ArticleDOI
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
TL;DR: In this article, the authors provide the first direct comparison of complex 3D micro cracking initiation and propagation in heterogeneous quasi-brittle materials modelled by the phase field numerical method and observed in X-ray microtomography images recorded during in situ mechanical testing.
