Abstract
Crack propagation is an evolutionary geometry problem. To simulate the arbitrary growth of 3D cracks with the finite element method requires many incremental geometry and corresponding mesh changes. The nature of crack front fields, and the complex geometries that can evolve also put special demands on meshing. I will focus my talk on two things:

• These demands and how we are meeting them in the Cornell Fracture Group: solved and unsolved problems will be highlighted through real-world application problems.

  and

• The rising competition from so-called meshfree methods for this class of problem. We mesh types better solve our technical and image problems soon, or...
