Material testing

The tensile test is used to determine the strength (yield point, ultimate tensile strength) and toughness (elongation at break) of a material! https://www.youtube.com/watch?v=nOdcE2pJx2A Setup The tensile test is one of the most important testing...

Ultrasonic testing uses sound waves to non-destructively inspect a component for flaws. Introduction Ultrasonic testing is a non-destructive testing technique because the workpieces or components to be tested are not damaged during the...

In the cupping test according to Erichsen, the deep drawing behavior of a metal sheet is examined. Sheets for deep-drawing applications must have very good cold formability, i.e. they must be able...

In a bending flexural test, a standardized specimen is bent under uniaxial bending stress until plastic deformation or fracture occurs! https://www.youtube.com/watch?v=B-caaAtTsDk Test setup In the bending flexural test, a specimen is loaded under uniaxial...

The creep rupture test (stress rupture test) is used to measure the strength of materials that are subjected to constant stress at elevated temperatures. Creep If components are subjected to a constant tensile...

With the Brinell hardness test, a carbide ball is pressed into the material. The indentation surface serves as a measure of the hardness! https://www.youtube.com/watch?v=bXV6ZimFzws Introduction In many applications, components should have not only a...

In the compression test, a standardized specimen is loaded under compressive stress until it breaks or until a first crack appears. The testing of materials under compressive stress is carried out in...

Eddy current testing is used to non-destructively inspect components for surface defects such as cracks. With eddy current testing, electrically conductive materials can be examined for pores, inclusions and cracks in the...

The fatigue test provides information about the strength of a material under continuously changing stress (dynamic load). https://www.youtube.com/watch?v=V2FItB2m4lk Introduction The intensity of the stress increases slowly but steadily in the tensile, compression and flexural...

In the Rockwell hardness test, an indenter is pressed into the material. The indentation depth serves as a measure of the hardness! https://www.youtube.com/watch?v=bXV6ZimFzws In the Rockwell hardness test, the measure of the hardness...

In the Vickers hardness test, a four-sided diamond pyramid is pressed into the material. The indentation surface serves as a measure of the hardness! https://www.youtube.com/watch?v=bXV6ZimFzws For the Vickers hardness test, a square base...

Fatigue limit diagrams according to Haigh or Smith show the maximum yieldable stress amplitude as a function of the mean stress. https://www.youtube.com/watch?v=pMUbK2DTJRs Fatigue limit diagrams Although the Wöhler curve is suitable for the evaluation...

With magnetic particle inspection (MPI), surface defects such as cracks of ferromagnetic components are made visible. Introduction Like the dye penetrant inspection, magnetic particle inspection is also a method for examining surface defects...
