Fracture mechanical testing

In principle fracture mechanical studies enable a quantitative description of the material damage caused by crack formation and crack propagation by utilising continuum-mechanical failure analysis. In order to fully exploit the potential created by new or already existing construction materials, it is necessary to utilise calculation and testing methods which are already available and/or develop new testing methods, which are able to represent the behaviour of a component under real-time operating loads and stresses as far as physically possible and guarantee an adequate level of safety vis-à-vis the various possibilities for failure. Especially in view of the ever increasing safety requirements, but also with regard to the efficiency and conservation of resources, an exclusive design of components and structures on the basis of classical strength gauges (i.e. without taking material and/or component imperfections into account) is no longer up-to-date.

On the contrary, cracks which could occur either as a result of the manufacturing process or by stress or load during operation must be considered in the design. The evaluation of cracks and/or crack-like imperfections in construction parts and components is indispensable for determining fracture mechanical parameters such as, for example, the threshold value behaviour or the crack resistance behaviour as the fracture mechanical analysis of fictional and real existing cracks must be increasingly considered as additional safety within the component design process.

We can determine the following characteristic values and parameters for you according to the concepts of linear elastic fracture mechanics (LEFM) and flow fracture mechanics (FFM):

Non-standardised Tests, and Special Tests

We are well known for being able to master every technical testing challenge. Our experts from the department for special test material possess a high level of expertise for non-standard materials and component testing. They can describe the intended function of the parts – we then develop the testing concept, organise the necessary test and measurement technology, take care of the calibration of the sensors, implement the testing and provide you with the final test report. Flexible accreditation from DAkks (German Accreditation Body) enables us to test materials and components according to different standards, as well as developing new testing procedures.

You are always welcome to send us requests regarding specific tests which you have not found in our test portfolio. We will then investigate whether we can support you in terms of the requested test.

Expertise

Cases of damage due to component failure or fire can cause you economic impairment. You therefore require assistance when searching for the causes or the planning follow-up measures for such cases. We can provide you with our expertise for a basis for expert assessments or during insurance negotiations.
