X-FEM implementation in Abaqus

Dear all,

Just in case it is of interest to some of you, we provide links to three postprints related to our Abaqus implementation of the X-FEM. The latest is an "article in press" in Eng Frac Mech where we explain the essentials of the implementation and provide a link to the source code for the Abaqus computation. Note that the implementation is limited to 2D and the pre-processing code needed for element subdivision is not provided.

The other papers are an application to crack growth under fretting fatigue conditions (published in IJSS) and a specific enrichment of the singularity of a sliding corner (published in IJNME). We hope that these three publications may be helpful.
