| dc.description.abstract | A new history independent thin plate Fiber Bundle Model is derived in or-
der to model in-plane material fracture. The model provides an easy way
of studying the not yet fully understood fracture processing zone.
Only considering relatively small system sizes, the model seems to be con-
sistent with experimental observations, giving a large scale roughness ex-
ponent of 0.27 ± 0.06.
No direct value was obtained for the small scale regime. However, its be-
havior and estimated fractal dimension is believed to be consistent with a
small scale roughness exponent of 2/3,
described by gradient percolation.
The high velocity tail of the velocity distribution of the fracture front, seemed
to be consistent with a power law with an exponent of -0.75 ± 0.07.
This is, however, not consistent with the experimental value of -2.55 ± 0.15. | |
