Life expectancy predictions via microstructure-based models

Assessment of Materials and Lifetime Concepts

We assess the influence of microstructures, internal stresses and damage on component functionality and life expectancy. We are particularly interested in linking specific analyses and experiments to advanced material models and in understanding the demands placed on our clients’ components. Our work is focused on modeling cyclical thermomechanical loads and on identifying the degradation mechanisms involved in corrosion, stress corrosion cracking and hydrogen embrittlement. In acute cases of damage, we can carry out surveys for our clients.

Microstructure and Residual Stresses


We investigate the effect of manufacturing processes and operational loads on the microstructure and the internal stress in materials and components. A particular focus lies on the identification of the ...

Lifetime Concepts and Thermomechanics

Motor components, aircraft turbines, power station and plant components are all subject to high thermal and mechanical loads. It often takes numerous expensive and time-consuming laboratory and field tests ...
