Booking ConditionsCourse description
- General introduction Overview of failure behaviour of cracked bodies; the influence of crack size, brittle behaviour; ductile behaviour; influence of material properties; cyclic loading and chemical environment. Thermodynamic criteria and energy balance- Griffith approach, modifications by Orowan. Strain energy release rate. Compliance. Applications to fibre composites. Stress requirements for fracture.
- LEFM and crack tip stress fields, stress concentration, stress intensity, plane stress and plane strain; fracture toughness in metallic materials; fracture toughness testing; calculations of critical defect sizes and failure stress. Crack tip plastic zones. The HRR field; CTOD, J; elastic-plastic failure criteria; defect assessment failure assessment diagrams.
- Fracture of rigid polymers and standard tests for fracture resistance of polymers. Delamination fatigue tests. Emerging CEN/ISO standards, current ESIS test procedures. Crack extension under cyclic loading; regimes of fatigue crack growth; influence of material properties and crack tip plastic zones; calculation of crack growth life and defect assessment in fatigue; crack closure and variable amplitude loading; short cracks and the limits of LEFM; software design tools for fatigue crack growth. Static loading-stress corrosion cracking; corrosion fatigue.
On completion successful delegates will:
- be familiar with the different regimes and processes of failure of cracked bodies and to understand the factors controlling them and the boundaries and limits between them.
- know and understand the principles of linear elastic fracture mechanics (LEFM) and their application to cracks in brittle, ductile and fibre composite materials through calculation of static failure conditions.
- calculate the limits of applicability of LEFM and apply modified predictive tools such as elastic-plastic fracture mechanics and failure assessment diagrams for calculation of failure.
- know how to apply fracture mechanics to failure of cracked bodies under cyclic loads and under aggressive chemical environments to predict service lives.
- generate laboratory fracture mechanics data; to be able to critically assess its validity for application to particular engineering situations.
