Content of Lecture:

Application, analysis and discussion of basic and advanced testing methods to ensure correct selection of applicable testing procedure for investigation of part/materials deficiencies.


The focus of the lecture lies on:

  • Stress-strain relationships
  • Strain gauge application
  • Visco elastic behavior
  • Tensile test (strain hardening, necking, strain rate)
  • Compression test, bending test, torsion test
  • Crack growth upon static loading (J-Integral)                                
  • Crack growth upon cyclic loading (micro- und macro cracks)
  • Effect of notches
  • Creep testing (physical creep test, influence of stress and temperature, Larson Miller parameter)
  • Wear testing
  • Non destructive testing application for overhaul of jet engines#
