Content of Lecture:

Application and analysis of basic mechanical as well as non-destructive testing of material.

The focus of the lecture lies on:

• Determination elastic constants                                                                                                                    

• Tensile test

• Fatigue test (testing with constant stress, strain, or plastiv strain amplitude, low and high cycle fatigue, mean stress effect)

• Crack growth upon static loading (stress intensity factor, fracture toughness)

• Creep test

• Hardness test

• Charpy impact test

• Non destructive testing
