Local residual stress analysis on strongly textured material



  • The application of the hole drilling is up till now limited to a residual stress analysis on isotropic material states.


  • Extending the application of the incremental hole drilling method for highly anisotropic (single cirstalline, coarse grained, highly textured) material states


  • Experimental determination of  residual stress in anisotropic material states under defined external load
  • Comparison with complementary methods (X-Ray diffraction)
  • FEM-Simulation of strain release during the application of the hole drilling method on anisotropic material states
  • Development of  a measurement and evaluation strategy
