Local residual stress analysis on strongly textured material

N.N.

Motivation

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

Objective

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

Analysis

• 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
