Component Assessment and Reliability


Applied research and services for theoretical component and condition assessment

Your professional partner for safety analyses

We offer you comprehensive consulting in the range of computational analysis and condition assessment for mechanical and plant engineering as well as civil engineering. Our services in the range of mechanical and plant engineering cover all aspects from numerical analysis via fatigue analysis through to fracture mechanics and reliability assessment. Our services in the range of civil engineering include condition assessment of engineering structures. We will be pleased to provide you with personal and individual advice.

The Units in our Department

Integrity Assessment and Structural Durability

We offer you numerical and analytical calculations for the static strength and fatigue strength of components in mechanical and plant engineering. We carry out our calculations using both commercially available finite element programmes and our own in-house calculation tools. We apply current standards and regulations to evaluate the fatigue strength. Our field of activity includes isothermal mechanical, thermal and thermo-mechanical fatigue.

Reliability and Probabilistic Assessment

We offer you reliability analyses by using probabilistic methods. We mainly deal with topics in the range of life cycle management of industrial facilities (e.g. power and process plants). For your risk-based maintenance and inspections, we carry out complete risk analyses and create corresponding risk matrices for your plant.

Fatigue Testing

Experimental Testing with cyclic loading of material samples and components are used for the determination of design factors. Compression, tension and bending as well as torsion and inner pressure can be applied. Also the impact of environmental exposure (medium, temperature, …) can be integrated in our test results. Stress and strain behavior can be recorded as well as the time- or cycle-dependent redistribution as well as damage development (crack initiation, crack propagation)

Tasks and technical focus

  • Numerical analysis of components in mechanical and plant engineering by use of finite element methods (FEM)
  • Fracture mechanics calculations of components in mechanical and plant engineering by use of FEM and Xpipe
