Puck Failure Criterion

It is based on Mohr‘s fracture hypothesis which is appropriate for brittle fracture behaviour of composite materials. It can distinguish between fibre fracture and different inter-fibre fracture. Both 2D and 3D formulations are implemented into Carat++. Available fracture modes for 2D Puck Criterion are:

  • Fibre Fracture (FF)
  • Inter Fibre Fracture Mode A (IFF A)
  • Inter Fibre Fracture Mode B (IFF B)
  • Inter Fibre Fracture Mode C (IFF C)

Available fracture modes for 3D Puck Criterion are:

  • Fibre Fracture (FF)
  • Inter Fibre Fracture (IFF)
