In-Plane Compressive Behaviour of Stiffened Thin-Skinned CFRP Panels with a Stress Concentrator

Soutis-Fleck Fracture Model
Unstable Fracture (Energy Based)
  • The unstable fracture stress is a function of the panel's geometry and the stress intensity resulting from the stress concentrator.

  • Panel Strength is determined from the intersection of the stable and unstable fracture curves.
