Effective toughness of disordered brittle solids: A homogenization framework
Towards brittle materials with tailored fracture properties: the decisive influence of the material disorder and its microstructure
Considering a semi-infinite crack propagating within a plane where the local fracture energy fluctuates due to the presence of microstructural heterogeneities, we emphasize the decisive influence of…
Effective Toughness of Heterogeneous Materials with Rate-Dependent Fracture Energy.
TLDR
These measurements demonstrate the applicability of the classical equation of motion of cracks at a discontinuity of fracture energy: the crack speed jumps at the entrance and exit of an obstacle, as predicted by the crack-tip energy balance within the brittle fracture framework.
Numerical fracture mechanics based prediction for the roughening of brittle cracks in 2D disordered solids
The behavior of fractures in 2D brittle disordered materials results from the competition between the microstructural disorder that roughens cracks and the material elasticity that straightens them.…
Crack-path selection in phase-field models for brittle fracture
This work presents a critical overview of the effects of different aspects of model formulation on crack path selection in quasi-static phase field fracture. We consider different evolution methods,…
Dynamice fracture in a semicristalline polymer: an analysis of the fracture surface
The fracture behaviour of a specific material, a semi-crystalline biobased polymer, was here studied. Dynamic fracture tests on strip band specimens were carried out. Fracture surfaces were observed…
Dynamic fracture in a semicrystalline biobased polymer: an analysis of the fracture surface
The fracture behaviour of a semi-crystalline bio-based polymer was studied. Dynamic fracture tests on strip band specimens were carried out. Fracture surfaces were observed at different scales by…
Computing the effective crack energy of heterogeneous and anisotropic microstructures via anisotropic minimal surfaces
A variety of materials, such as polycrystalline ceramics or carbon fiber reinforced polymers, show a pronounced anisotropy in their local crack resistance. We introduce an FFT-based method to compute…

Influence of heterogeneities on crack propagation
The influence of material heterogeneities is studied in the context of dynamic failure. We consider a pre-strained plate problem, the homogeneous case of which has been widely studied both…
Brittle fracture and fatigue propagation paths of 3D plane cracks under uniform remote tensile loading
Fatigue and brittle fracture propagation paths of arbitrary plane cracks, loaded in mode I, embedded in an infinite isotropic elastic body, are investigated. The crack advance is supposed to be…
