Crack Growth Simulation on a Compression-Loaded Blade

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.

DEFINITION OF THE PROJECT

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

CALCULATION

• 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
