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#
