Material modeling and simulation
Fraunhofer Institute for Mechanics of Materials IWM
Reproducing load scenarios and processes for existing or planned materials and components on the computer.
Computer simulations are indispensible for avoiding trial-and-error loops in the process of component development, for depicting complex load scenarios or for predicting the operational behavior of existing materials and components or those that are currently under development. This is why we have become experts at material modeling on various scales (multi-scale modeling) and the measurement of model-specific properties (Design of Experiments). We use these skills to describe the deformation, damage, fracture and functional behavior of materials.
We use our virtual testing laboratory to calculate the safety and operational life of components. Process simulations enable us to design tools to meet the loads and to improve process controls. Our virtual microscope enables us to assess and optimize the functions of new materials.
