Fracture mechanics is used in engineering to establish acceptance levels for flaws revealed using non-destructive examination techniques.
Why is this important? If your machinery or structure needs to be operating continually, you must determine its fitness for purpose.
A mechanical structure is considered adequate for its purpose if the conditions to cause its failure are not reached.
Deacon Engineers have the expertise to carry out flaw assessments on a fitness for purpose basis by offering post-crack initiation study services to API 579 and BS 7910.
We have the expertise to carry out the following post-crack-initiation studies:
- Stress intensity factor calculation
- Fatigue crack growth rate calculation
- Critical crack size determination
- Crack path prediction
- Residual strength calculation
- Contact load redistribution during crack growth
- Incorporation of effects of thermal stresses in crack growth simulation
