Effect of Crack Blunting on Subsequent Crack Propagation [PDF]
Theories of toughness of materials depend on an understanding of the characteristic instabilities of the crack tip, and their possible interactions. In this paper we examine the effect of dislocation emission on subsequent cleavage of a crack and on ...

Phase field modelling of crack propagation, branching and coalescence in rocks
We present a phase field model (PFM) for simulating complex crack patterns including crack propagation, branching and coalescence in rock. The phase field model is implemented in COMSOL and is based on the strain decomposition for the elastic energy ...

Mechanisms during Strain Rate-Dependent Crack Propagation of Copper Nanowires Containing Edge Cracks
The crack propagation mechanism of Cu nanowires is investigated by using molecular dynamics methods. The microstructural evolution of crack propagation at different strain rates and crack depths is analyzed.

Propagation behavior of two collinear mode Ⅰ cracks driven by explosive gas
In smooth pre-splitting blasting, two collinear cracks extending opposite to each other between adjacent holes will first avoid each other and then attract each other, resulting in crack propagation path that often presents hooked or butterfly-shaped ...

Crack Propagation in Quasicrystals [PDF]
Crack propagation is studied in a two dimensional decagonal model quasicrystal. The simulations reveal the dominating role of highly coordinated atomic environments as structure intrinsic obstacles for both dislocation motion and crack propagation. For certain overloads, these obstacles and the quasiperiodic nature of the crystal result in a specific ...

Crack-Net: Prediction of Crack Propagation in Composites
Computational solid mechanics has become an indispensable approach in engineering, and numerical investigation of fracture in composites is essential as composites are widely used in structural applications. Crack evolution in composites is the bridge to elucidate the relationship between the microstructure and fracture performance, but crack-based ...
