- Loading Condition:
Compressive Displacement Control applied parallel
to stiffeners
- Boundary Conditions:
Sides parallel to stiffeners are free. Remaining Sides
are fully clamped.
- 15 J impact damage in skin bay replaced by an open
hole. This model provides the stress distribution
adjacent to the hole.

Stable Fracture FE model
– Compressive loading in vertical direction. |
- Loading Condition:
Tensile Displacement Control.
- Crack is introduced by disconnecting appropriate
nodes along crack line.
- The models created for each crack length provide
the strain energy levels in each state.
