Material and Component Deformation and Failure Behavior


The focus here revolves around the evaluation of safety as well as the suitability for use of components with high safety requirements under operationally relevant loads. The range of applications extends from the safety verification of power plant components, fault tolerance verification of aerospace components, service life analysis of thermomechanically stressed components in power plants and automobiles and crash analyses of vehicle components. In addition to the application behavior of modern materials, joints, joining and hybrid construction methods are of central importance. We develop and use mechanism-based material models to describe the deformation and failure behavior of components under thermal and mechanical stress.


Material deformation, damage and crack formation

Dr. Michael Luke illustrates how material deformation, damage and crack formation affect component functionality and service life.

Assessment of Materials and Lifetime Concepts 


Hydrogen can enter materials through various processes - through loading with gaseous hydrogen and through electrochemical processes such as corrosion or galvanic coating. The topic of hydrogen embrittlement of metals is becoming increasingly important in the transport and energy sector, as hydrogen is seen as one of the most important future sources of energy. The associated development of new technologies for the production, distribution and use of hydrogen as an energy source requires the qualification of existing and newly developed materials for these applications. For this reason, the Fraunhofer IWM has developed novel test rigs for hydrogen embrittlement in metals - a hollow sample test rig and an autoclave for hydrogen loading with in situ testing of samples.

Dr. Ken Wackermann demonstrates the importance of hydrogen embrittlement testing.

Digitalization within materials technology 


Materials data and information hold a huge potential for value creation and innovation. The key to success is to digitally map materials with their properties, functions and behavior. By making information on changing material properties in the product life cycle consistently available and by incorporating material science evaluation into production, new design possibilities are opening up for the reliability and functionality of components as well as the efficiency of manufacturing processes.

The Fraunhofer IWM has set itself the goal of standardizing and facilitating the handling of materials information. Together with strategic project partners, initial frameworks for this are being developed in current lighthouse projects. These frameworks are intended to structure decentralized materials data in a uniform way – and critically to make it accessible - while of course ensuring data security and data sovereignty.


The digital twin in materials technology 

The digitalization of materials makes an important contribution to ensuring that materials become part of the digitally integrated and networked value chain.

Materials Design 


Atomistic simulation methods can help to replace materials such as rare earth elements through the search for alternative materials. With simulations based on solid state physics and material-mechanical experiments, we clarify materials behavior and predict material properties. This enables us to design materials structures and functions in a targeted manner. We use this knowledge to identify resource and energy-efficient combinations of materials that will improve technical systems in the long term.
