Branching mechanism of intergranular crack propagation in three dimensions.
نویسندگان
چکیده
We investigate the process of slow intergranular crack propagation by the finite element method model and show that branching is induced by partial arresting of a crack front owing to the geometrical randomness of grain boundaries. A possible scenario for the branching instability of crack propagation in a disordered continuous medium is also discussed.

Molecular - dynamics simulation - based cohesive zone representation of intergranular fracture processes in aluminum
A traction-displacement relationship that may be embedded into a cohesive zone model for microscale problems of intergranular fracture is extracted from atomistic molecular-dynamics simulations. A molecular-dynamics model for crack propagation under steady-state conditions is developed to analyze intergranular fracture along a flat Σ99 [1 1 0] symmetric tilt grain boundary in aluminum. Under hy...
متن کاملStudy of the branching instability using a phase field model of inplane crack propagation
In this study, the phase field model of crack propagation is used to study the dynamic branching instability in the case of inplane loading in two dimensions. Simulation results are in good agreement with theoretical predictions and experimental findings. Namely, the critical speed at which the instability starts is about 0.48cs. They also show that a full 3D approach is needed to fully underst...
متن کاملMolecular Dynamics Simulations of Crack Propagation
Crack propagation is studied in a two-dimensional binary model-quasicrystal by molecular dynamics simulations. Three regimes of motion can be discerned: An intermittent regime with stop and go, a regime of steady motion and an unstable regime with branching. In the rst two regimes the crack tip is emitting disloca-tions, which are followed by a phason wall. Along this wall the material is openi...
متن کاملA boundary element analysis of crack-propagation mechanism of micro-cracks in rock-like specimens under a uniform normal tension
In this work, the mechanism for fracture of brittle substances such as rocks under a uniform normal tension is considered. The oriented straight micro-cracks are mostly created in all the polycrystalline materials resulting from the stress concentrations. The present work focuses on the interactions of the pre-existing micro-cracks, which can grow and propagate within a rock-like specimen. The ...
متن کاملFractographic Aspects of Stress Corrosion Failure of Zircaloy 2 in CH3OH HCL Solutions
Fracture surface of Zircaloy-2 specimens tested under constant crosshead speed in CH3OH/0.4 Vol. %HCI solution with and without selenium (25 ppm) addition was studied. Using a combined process of deformation and annealing, coarse grained material was also obtained and examined. Two modes of stress corrosion crack propagation were observed: an intergranular zone caused by stress assisted anodic ...
