Extrinsic cohesive modelling of dynamic fracture and microbranching instability in brittle materials
Dynamic crack microbranching processes in brittle materials are investigated by means of a computational fracture mechanics approach using the finite element method with special interface elements and a topological data structure representation. Experiments indicate presence of a limiting crack speed for dynamic crack in brittle materials as well as increasing fracture resistance with crack spe...
متن کاملIdeal Brittle Fracture of Silicon Studied with Molecular Dynamics
Silicon is very brittle and a wafer dropped on the floor easily shatters. A clue to explaining why comes from static cracks. Even at room temperature, static cracks in silicon can have tips that are atomically sharp [1], and there is every reason to believe that crystals can be severed very efficiently by the propagation of such sharp cracks. Relations between crack speed and energy consumption...
متن کاملOn an Eigendeformation Approach to Brittle Fracture
The paper presents a numerical implementation of a novel approximation scheme for Griffith’s theory of brittle fracture recently proposed in [1]. The total potential energy of a brittle body (including bulk and surface terms) is variationally approximated by a family of functionals, depending on a small penalty parameter ε. The (two-field) approximating functionals have as arguments the displac...
متن کاملAn eigenerosion approach to brittle fracture
The present work is concerned with the verification and validation of a variant of the eigenfracture scheme of Schmidt et al. (2009) based on element erosion, which we refer to as eigenerosion. Eigenerosion is derived from the general eigenfracture scheme by restricting the eigendeformations in a binary sense: they can be either zero, in which case the local behavior is elastic, or they can be ...
متن کاملFractal Dimension of Brittle Fracture
Using a worldwide catalog of earthquakes we analyze the distribution of distances between pairs of earthquake hypocenters to determine the spatial fractal dimension 6 of an earthquake fracture. As the time span of the catalog increases, 8 asymptotically reaches the value 2.1-2.2 for shallow earthquakes. Approximately the same asymptotic value of dimension is obtained for a catalog of earthquake...
