Typical application areas


Zencrack can be applied in any industry in which knowledge of crack behaviour, crack growth prediction and residual life calculation are important issues, e.g.:

  • aerospace
  • nuclear
  • manufacturing
  • offshore
  • power generation.


Within any of these industries, a fracture mechanics analysis may be used in many different situations, e.g.

  • post-failure and accident investigations
  • forensic studies
  • parametric studies of different crack sizes in a component
  • leak before break studies
  • design of experiments
  • generation of failure assessment diagrams
  • determination of -
    • the residual life of a component with a known flaw size and load history
    • the maximum crack size for a given life
    • NDT inspection periods
    • repair scenarios
    • threshold crack size for a given cyclic load.


On a task-based or component level the potential use of the software is almost unlimited. Typical applications include:

  • assessing residual life
  • life extension
  • damage tolerance assessment
  • reliability analysis
  • development of new materials
  • elastic and plastic analysis to show interaction between ductile and brittle failure (i.e. failure assessment diagram methodology)
  • engine disks and blades and their dovetail connections
  • power generation components, e.g. high pressure waterbox
  • pipeline defects and connections, e.g. tee, sweepolet connections
  • rail tracks
  • welded connections
  • rubber components
  • high temperature creep Ct integral evaluation
  • adhesive bonded patch repairs
  • maintenance scheduling.
