Branching mechanism of intergranular crack propagation in three dimensions.
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.
متن کاملDiscrete element modeling of brittle crack roughness in three dimensions
*Correspondence: Bjørn Skjetne, Department of Physics, Norwegian University of Science and Technology, N-7491 Trondheim, Norway e-mail: [email protected] Crack morphology obtained in the fracture of materials with a disordered micro-structure is studied using numerical simulations. Physical properties are embedded on a regular three dimensional lattice as discrete stochastic elements which confo...

15 صفحه اولFront Tracking in Two and Three Dimensions
Front Tracking is the combination of two distinct computational traditions. Its purpose is to enable high quality, relatively coarse grid mesh solutions for problems complicated by the presence of fronts, interfaces, and other discontinuities, which may be of considerable geometric complexity. The rst of the two algorithmic ideas used in front tracking is upwind diierencing, for uids, materials...
