of cracks and develop the remedial strategy.

periods
Engineers frequently need to investigate
the cause of cracks and distinguish between design,
fabrication and in service damage. Computer modelling
of crack growth provides quantative and qualative
data to support an investigation. Specifically:
Forensic
Investigation
When a part has failed or damage has been observed during maintenance, a virtual
prototype of the component can be developed. Quantitative data on the stress
intensity factors, crack growth rates and growth path predicted. The impact of
remedial measures can also be assessed.
The stress intensity
factors along the crack front can be predicted as well
as the crack path.
Simulating
the failure mode
The failure mode can be simulated under different loadings and conditions and
the criteria for future inspection strategies can be determined. For example,
what crack size is acceptable for future
operations?
In this application a model was
used to determine the critical
loading and material parameters
required to reproduce the crack
behaviour.
