چکیده
This work presents concepts and algorithms for the simulation of dynamic fractures with a Lattice Boltzmann method (LBM) linear elastic solids. LBM has been presented previously solves wave equation, which is interpreted as governing equation antiplane shear deformation. Besides steady growth crack at prescribed velocity, fracture criterion based on stress intensity factors (SIF) implemented. first time, that propagation mechanically relevant regarded in context LBMs. Numerical results are examined to validate proposed method. The introduced here not limited mode III cracks or simplified deformation assumption shear. By introducing rather simple processing step into existing level individual lattice sites, overall performance maintained. Our findings underline validity numerical tool simulate solids general well particular.

A lattice Boltzmann method for shock wave propagation in solids
This paper proposes a new lattice Boltzmann (LB) method for the study of shock wave propagation in elastic solids. The method, which implements a flux-corrected transport (FCT) algorithm, contains three stages: collision, streaming, and correction. In the collision stage, distribution functions are updated. In the streaming stage, the distribution functions are shifted between lattice points. G...
متن کاملSteady-state mode III cracks in a viscoelastic lattice model
We extend the Slepyan solution of the problem of a steady-state crack in an infinite ideally brittle lattice model to include dissipation in the form of Kelvin viscosity. As a demonstration of this technique, based on the Wiener-Hopf method, we apply the method to mode III cracks in a square lattice. We use this solution to find the critical velocity at which the steady-state solution becomes i...
متن کاملDynamic Behavior of an Oil Droplet Adhered to the Wall Surface in a Channel Flow by the Lattice Boltzmann Method
The Lattice Boltzmann Method is used to simulate the dynamics of droplet deformation in a channel flow under various conditions. The droplet behavior has been investigated under transient conditions. For cases where the droplet remains attached to the surface, the shape deformation of the droplet during crawling is captured. It has been shown that there is a limiting value for the droplet volum...
متن کاملA Simplified Curved Boundary Condition in Stationary/Moving Boundaries for the Lattice Boltzmann Method
Lattice Boltzmann method is one of computational fluid dynamic subdivisions. Despite complicated mathematics involved in its background, end simple relations dominate on it; so in comparison to the conventional computational fluid dynamic methods, simpler computer programs are needed. Due to its characteristics for parallel programming, this method is considered efficient for the simulation of ...
متن کاملA novel boundary condition for the simulation of the submerged bodies using lattice boltzmann method
In this study, we proposed a novel scheme for the implementation of the no-slip boundary condition in thelattice Boltzmann method (LBM) . In detail , we have substituted the classical bounce-back idea by the direct immersed boundary specification . In this way we construct the equilibrium density functions in such a way that it feels the no-slip boundaries . Therefore , in fact a kind of equili...
