No worries! Check out the recording and learn how Abaqus FEA provides proven robust capabilities for modeling bulk fracture and crack propagation in many materials. One of the newest techniques available in Abaqus is the eXtended Finite Element Method (XFEM) whose advantages over alternative approaches include mesh independent crack definition, improved convergence rates for stationary cracks, simplified mesh refinement studies and more!

Hi,
I have used XFEM in Abaqus for static analysis. I use traction-separation cohesive behavior with XFEM.
I want to use XFEM in implicit dynamic analysis. I am using Abaqus version 6.12. As far as I know xfem was allowed only with static analysis in earlier Abaqus versions (6.9). I read that the newer versions have implicit dynamic analysis compatiblity with XFEM.
I am using XFEM in ABAQUS to simulate crack growth from one material to another. Although the crack passes through the interface, the simulation stops after crack growth of few more elements with this error:
"THE FRACTURE CRITERION f=1.5400 AT ELEMENT 2469, THE DAMAGE INITIATION TOLERANCE HAS BEEN EXCEEDED AND CUTBACK IS REQUIRED."
This element is the one right next to the crack front.
I have tried to increase the damage initiation tolerance > 0.5 and the crack grows one more element and then same error.
Hi All
I am trying to obtain SIF value for a stationary crack using XFEM in Abaqus.
I am using the 5th contour value and plotting against distance from crack front using excel.
The values are from History Output.
I am getting a very funny graph that is going up and down.
Hi
I am new to modelling and am trying to model a plate with a middle crack using Abaqus.
What is the difference between modelling a cohesive and LEFM crack growth (I know cohesive involves plasticity and the traction/displacement curve and LEFM is for brittle materials).
For cohesive, I used max principal stress for damage criteria and damage evolution based on energy criteria.
Hellow everyone,
I've been studying XFEM method in Abaqus these days, then i want to model an inclusion problem to see the crack initiation and propagation at the interface. First i sketch a square to stand for a unit cell, then in order to assign different sections to inclusion and matrix, i cut a circle (circular inclusion) from the initial square. But when it comes to meshing, i don't know how to mesh the instance with structral quad elements independantly of the outline of the inclusion. Could anyone help me?
