  Partition of unity methods (PUM) are of domain decomposition type and provide
the opportunity for multiscale and multiphysics numerical modeling. Within the
PUM global-local enrichment scheme [1, 2] different physical models can exist
to capture multiscale behavior. For instance, we consider classical linear
elasticity globally and local zones where fractures occur. The elastic fields
of the undamaged media provide appropriate boundary data for local PD
simulations on a subdomain containing the crack tip to grow the crack path.
Once the updated crack path is found, the elastic field in the body and
surrounding the crack is updated using PUM basis with appropriate enrichment
near the crack. The subdomain for the PD simulation is chosen to include the
current crack tip as well as nearby features that will influence crack growth.
This paper is part II of this series and validates the combined PD/PUM
simulator against the experimental results presented in [3]. The presented
results show that we can attain good agreement between experimental and
simulation data with a local PD subdomain that is moving with the crack tip and
adaptively chosen size.
