Service Loading Fatigue and Structural Integrity
The Service Loading Fatigue and Structural Integrity division tests specimens to identify material properties, for which we work in accordance with various sets of regulations or our clients' requirements.
We assess and characterise materials in accordance with these regulations or on the basis of in-house experience. We test components and systems to determine their resilience. With the acquisition and execution of research projects, we develop the scientific knowledge and technical expertise of our division further.
We also analyse and assess mechanical engineering failure on behalf of industrial enterprises, courts of law and public prosecutors. We develop constitutive models, both for materials and for predicting product lifetimes. We convey our findings to the wider scientific and engineering community through publications and presentations.
Fields of expertise
- Performance of service loading fatigue and fracture mechanics tests and acquisition of information regarding component safety and reliability
- Identify the effect of materials, design, production, environmental conditions and stresses on the fatigue strength of components and systems and determine the impact of these on damage
- Analyse and refine material and damage models as well as failure concepts and incorporate these into finite element programmes
- Simulate sample and component behaviour including damage patterns under non-elastic loading conditions
- Fracture mechanics and component safety
- Service Loading Fatigue
- Failure analysis and prevention
Range of services/technical equipment
- Servohydraulic and mechanical testing devices and individual testing cylinders with test force ranges from 10 kN to 20 MN
- Circumferential bending testing station for a moment range of 80 Nm to 120 Nm
- Electrodynamic shakers for peak loads of 100 N to 26 kN
