Sažetak
The crack path and failure analysis of the blade in a gas turbine was investigated by fracture mechanical study using a numerical analysis. The Two fracture mechanics approach K-T is used to estimate the mechanical properties of the blade with semi elliptical defaults. In this analysis, the applied pressure is not constant, whereas is imported with a interaction between structure fluid. ANSYS Workbench 16.0 software were used with the computational fluid dynamics Software (CFD section), a steady state gas flow analysis was carried out, and the pressure distributions. In the structural analysis a node coordinate where we have the maximum principal stresses were explored. In this node, we have created a semi- elliptical crack and we have compared between them with the Stress Intensity Factors and T- stress values. The second parameter in the Williams' equation give a good information’s on the estimation and the direction of the crack path.
