Results Summary

 |
 |
|
Overall the results agree very well with experimental
observation. The Soutis-Fleck model predicts, on average,
87% of the panel failure stress. The most notable discrepancy
lies in the results of panel DERA type 2. A possible reason
for this may be due to the selection of the hole size
representing the damage area. It may be the case that
the damage area was overestimated or perhaps the volume
of fibre-breakage was relatively low. Remodelling the
plate with a soft inclusion to represent the damage area
may produce significantly better results. |
