Fraunhofer Institute for Microstructure of Materials and Systems IMWSA fatigue test is used at Fraunhofer IMWS in materials testing and materials engineering to evaluate the fatigue strength of materials. It tests how well a material withstands cyclic loading without failing.
The fatigue test usually involves applying a periodic mechanical load that constantly fluctuates between minimum and maximum stresses. This load can take the form of tensile, compressive, or bending stresses and is carried out in a controlled environment. The material is repeatedly subjected to these stress cycles, and the test runs for an extended period of time to determine how many cycles it takes for the material to fail.
The results of the fatigue test are presented in the form of a Wöhler diagram, which shows the number of cycles to failure as a function of the stress applied to the material. This diagram is useful for evaluating the fatigue strength of a material and is of great importance in design and engineering, as it helps to predict the durability of components and structures under real operating conditions.
Technical equipment for fatigue testing at Fraunhofer IMWS:
- 1 N to 250 kN
- temperature-controlled up to 10 kN
- maximum test speed of 1.5 m/s
- up to 200 Hz
