Brittle fracture Phase-field model Spatial variation of the regularisation length Adaptive mesh refinement 1. Introduction Understanding a material’s fracture is essential to design mechanical systems, particularly for components with a low safety factor. However, reliable fracture computations are difficult...
Continuum-scale multi-component reactive transport modeling is a well-established topic in the literature27. We use a phase-field model due to its capability to model fracture propagation without needing domain remeshing28,29,30,31,32. Several fracture phase-field models are proposed in the ...

Further, a specific phase field model for brittle fracture is reviewed, where we focus on the meaning of the auxiliary parameter differentiating between material phases and the coupling of such a parameter to continuum equations in order to obtain the characteristic self organizing model properties. ...

In this paper, we intend to develop a continuum theory of fracture nucleation in single-walled carbon nanotubes by incorporating interatomic potentials between carbon atoms into a continuum constitutive model for the nanotube wall. In this theory, the fracture nucleation is viewed as a bifurcation ...

including the lattice model [13], discrete element model [5], extended finite element method (XFEM) [22] and cohesive zone method [31], [33].The latter interprets the sharp crack to be still a smeared damage continuum or a diffusive crack. The phase-field method falls into this category...
Being able to seamlessly deal with complex crack patterns like branching, merging and even fragmentation, the phase-field model, amongst several alternatives, is promising in the computational modeling ofdynamic fracturein solids. This paper presents an extension of our recently introduced phase-fieldcoh...
