You can do the following to model fracture mechanics with
Abaqus/CAE:
Create a seam crack that defines an edge or a face with overlapping
nodes that can separate during an analysis.
Use contour integral estimates to study the onset of cracking in
quasi-static problems; however, a contour integral estimate does not predict
how a crack will propagate. You can compute contour integrals for two- or
three-dimensional models.
Use the extended finite element method
(XFEM) to study the initiation and propagation
of a crack along an arbitrary, solution-dependent path without needing to
remesh your model. XFEM is available only for
three-dimensional solid and planar models and orphan meshes.
Use the virtual crack closure technique
(VCCT) to study the initiation and propagation
of a crack along a known crack surface.
Use the Crack Manager to create and manage your
cracks.
