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

Structural Durability

We offer you numerical and analytical calculations regarding structural durability of components in mechanical and plant engineering. We carry out our calculations with commercial finite element software as well as in-house calculation tools. For structural durability assessment, we apply current codes and standards. Our scope of activities covers isothermal mechanical, thermal and thermo-mechanical fatigue.

Integrity Assessment

We offer you numerical and analytical calculations regarding static strength of components in mechanical and plant engineering. We carry out our calculations with modern numerical methods, conventional and analytical methods. For the assessment of static strength, we apply current codes and standards.

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.
