Quasi-static crack propagation with a Griffith criterion using a variational discrete element method
نویسندگان
چکیده
A variational discrete element method is applied to simulate quasi-static crack propagation. Cracks are considered propagate between the mesh cells through facets. The elastic behaviour parametrized by continuous mechanical parameters (Young modulus and Poisson ratio). energetic cracking criterion coupled a kinking guide process. Two-dimensional numerical examples presented illustrate robustness versatility of method.

Quasi-Static Crack Propagation by Griffith’s Criterion
We consider the propagation of a crack in a brittle material along a prescribed crack path and define a quasi-static evolution by means of stationary points of the free energy. We show that this evolution satisfies Griffith’s criterion in a suitable form which takes into account both stable and unstable propagation, as well as an energy balance formula which accounts for dissipation in the unst...
متن کاملA Study of the Wave Propagation Velocity in Granular Soils Using Discrete Element Method (DEM)
In the present paper, discrete element method (DEM) is used to study wave propagation phenomenon in granular soils. The effect of factors such as coefficient of friction, frequency, normal stiffness and soil gradation on the wave velocity is studied. Using the wall motion based on the sinusoidal function is the method of loading used in this simulation, through which the pressure wave is transf...
متن کاملThermal fracture as a framework for quasi-static crack propagation
We address analytically and numerically theproblemofcrackpathprediction in themodelsystem of a crack propagating under thermal loading.We show that one can explain the instability from a straight to a wavy crack propagation by using only the principle of local symmetry and theGriffith criterion.We then argue that the calculations of the stress intensity factors can be combinedwith thestandardcr...
متن کاملA two dimensional Simulation of crack propagation using Adaptive Finite Element Analysis
Finite element method (FEM) is one of the most famous methods which has many applications in varies studies such as the study of crack propagation in engineering structures. However, unless extremely fine meshes are employed, problem arises in accurately modelling the singular stress field in the singular element area around the crack tip. In the present study, the crack growth simulation has b...
