چکیده

We deal with the Ambrosio-Tortorelli approximation of the well-known Mumford-Shah functional to model quasi-static crack propagation in brittle materials. We employ anisotropic mesh adaptation to efficiently capture the crack path. Aim of this work is to investigate the numerical sensitivity of the crack behavior to the parameters involved in both the physical model and in the adaptive procedure.

The benefits of anisotropic mesh adaptation for brittle fractures under plane-strain conditions

We develop a reliable a posteriori anisotropic first order estimator for the numerical simulation of the Francfort and Marigo model of brittle fracture, after its approximation by means of the Ambrosio-Tortorelli variational model. We show that an adaptive algorithm based on this estimator reproduces all the previously obtained well-known benchmarks on fracture development with particular atten...

Anisotropic Mesh Adaptation for the Minimization of the Ambrosio- Tortorelli Functional with Application to Quasi-static Brittle Frac- ture Propagation

Francfort and Marigo presented in 1998 a model for quasi-static brittle fracture which requires the minimization of the Mumford-Shah functional, representing the energy of the system. The minimization of this functional represents a very challenging issue since it is non-smooth and non-convex. The numerical approximation of this problem can be issued via a Gamma-approximation on the energy func...

Universal Meshes for the Simulation of Brittle Fracture and Moving Boundary Problems

Universal meshes have recently appeared in the literature as a computationally efficient and robust paradigm for the generation of conforming simplicial meshes for domains with evolving boundaries. The main idea behind a universal mesh is to immerse the moving boundary in a background mesh (the universal mesh), and to produce a mesh that conforms to the moving boundary at any given time by adju...

Experimental, Franc2d, and DDM simulation to determine the anisotropic tensile strength of brittle material

In this paper, a compression-to-tensile load converter device is developed to determine the anisotropic tensile strength of brittle material. A cubic sample with an internal pore was used as the test specimen, and a series of finite element analysis and DDM simulations were performed thereafter to analyse the effect of pore dimensions on the stress concentration, as well as to render a suitable...

Analysis of Hessian Recovery Methods for Generating Adaptive Meshes

We study adaptive meshes which are quasi-uniform in a metric generated by the Hessian of a P1 finite element function. We consider three most efficient methods for recovering this Hessian, one variational method and two projection methods. We compare these methods for problems with anisotropic singularities to show that all Hessian recovery methods result in acceptable adaptive meshes although ...
