Fracture Model
Unstable Fracture (Energy Based)
- The microbuckle at the hole edge is assumed to behave
as a crack of the same length, with no traction on
the crack surfaces.
|
|
- The Model assumes that unstable crack growth occurs
when the stress intensity factor at the crack tip
equals the laminate in-plane fracture toughness.
