Material testing has a major influence on the rational use of materials and the design of components, as the material properties are influenced by production and processing. Mechanical or physical properties are described using material characteristics. The definitions of the most common material properties, their meaning and the test methods are discussed. The similarities but also specific differences in the material testing of plastics and metallic materials are conveyed theoretically and made comprehensible in selected practical experiments.

1. Motivation and purpose of materials testing
2. Production of test specimens
3. Mechanical properties: tensile test, bending test, hardness test,  impact test, static long-term test, dynamic test
4. non-destructive testing methods: Ultrasonic testing - Eddy current testing - X-ray testing
5. thermal properties: DSC, TGA, TMA, heat deflection temperature, test methods for determining flow properties

Practical course: -Hardness test -Impact bending test -Elastic constants -Tensile test -Dynamic testing -Ultrasonic testing -Eddy current testing -X-ray testing -Melt index testing

The total workload for the module is 150 hours (see also "ECTS credit points and grading").

In the practical laboratory course, students learn about and carry out plastics and metal-specific test procedures. The number of experiments is approx. 10. 

• Field work / Experimental work or
• oral exam

• Regular participation or
• Field work / Experimental work

The examiners choose the type of examination from the options provided and inform the students at the beginning of the semester.

If EA (experimental work) is selected as a graded examination, EA is omitted from the ungraded examination.

If the oral examination is selected as an examination, the EA is selected as an ungraded examination.

This module requires basic knowledge of materials technology for plastics and metals. In particular, prior knowledge in the field of physics is important.

Students at Osnabrück University of Applied Sciences who have successfully completed this module acquire a broad knowledge of the determination of technological material characteristics of metals and plastics. They understand the relationships between the test methods and the static, cyclic and dynamic characteristic values and are able to interpret these.

Students at Osnabrück University of Applied Sciences who have successfully completed this module have a detailed knowledge and understanding in the field of materials testing that corresponds to the current state of knowledge and research. They have basic knowledge of the testing methods used in industry for quality assurance. Accordingly, they are able to define test procedures, coordinate the production of samples, monitor the execution of tests and record them in an appropriate manner, taking into account the relevant standards. Based on the test results, students will be able to discuss and interpret material behaviour and give appropriate instructions for action against the background of a scientific question.

Students are able to analyse and interpret data sets and test results obtained through measurements and derive corresponding instructions for action against the background of a scientific question.

With the help of the knowledge acquired in the module, students are able to develop solution approaches to investigate material-specific issues with the help of suitable experiments.

Students can present their work results from the practical laboratory course in writing in a clearly structured form and respond verbally to questions.
