Fracture Mechanics Assessments

Fracture mechanics is used in engineering to establish acceptance levels for flaws revealed by the use of non-destructive examination techniques. This in turn leads to the concept of fitness for purpose. A mechanical structure is considered adequate for its purpose as long as 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 BS7910.

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
