Follow up course - Fall 2006 ME 436 Advanced
Fracture Mechanics
25
Could a machine operate safely with cracks?
  • All man made structures contain flaws or defects
    or cracks!
  • The question is, could we design structures so
    that they operate safely in the presence of known
    or unknown flaws?
  • Based on mechanics of materials approach, we
    cannot.

26
Mechanics of Materials Approach to Design
  • MoM Approach assumes that materials and
    structures are defect free.
  • Given two parameters, Applied Stress (loading)
    Strength (material property)

27
Fracture Mechanics Approach to Design
  • Fracture mechanics approach assumes that all
    materials and structures contain inherent
    flaws/cracks so failure occurs well below the
    static strength.
  • Three parameters appear in the fracture mechanics
    design methodology Applied Stress (loading),
    Fracture Toughness (material property) and Flaw
    size (quality control).

29
Fracture Mechanics - Objective
  • Since we cannot build defect free structures,
    we would like to
  • Calculate safe load for a known defect
  • Determine safe defect size for a given load
  • select a material for a design load defect
  • Determine safe operating life before a defect
    grows and results in a catastrophic failure.
  • Incorporate damage tolerance features so as to
    prevent catastrophic failures if an unexpected
    failure does occur

30
Fracture Mechanics - Objective
  • To learn to deal/live with cracks!!!
