Crack growth simulation

Crack growth simulation

 

Crack growth calculations become important whenever replacement of an existing component is not easy due to great effort. Here, crack growth simulation can prove suitability of a component for further operation.

The following example deals with a crack at the edge of a compression-loaded blade.

 

 Task / Calculation


  •  Calculation of the behaviour of an existing crack under continuous load
  •  Statement on further applicability of the component

 

 Target / Profit


  •  Determination of the pressures on the blade by CFD simulation
  •  Creation of a submodel of the crack's immediate
  •  Determination of crack growth

 

 Results


  •  Statements on how to repair the blade with possible measures for further operation
