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.

With simulative and experimental methods based on solid state physics and material mechanics, we clarify material behavior and predict material properties, which enable us to design material structures and functions. We uncover influences of crystal defects and microstructures on the material behavior on large scales. We use these findings to combine materials in a targeted manner in a resource and energy efficient manner, thus sustainably improving technical systems.
