Simulations in Lightweight Construction and Insulation Materials

This main focus is on functional design of fiber and particle reinforced lightweight components and insulating materials.

In lightweight construction, manufacturers rely on less mass. Weight is saved not only by using lighter materials, but also by integrating functions and designing designs that are more appropriate to the load and material. Since both the materials and the design, joining and manufacturing processes are continuously being developed and refined, goods are created with the same or even better properties than the original product.

Lightweight construction is already being used in many different ways today. In both the automotive and consumer sectors (e.g. drill housings), fibre and particle reinforced plastics are increasingly replacing metals as a material. In the construction, leisure and sports industry (e.g. sports shoe soles), foams are increasingly being used and in the furniture industry (e.g. Billy shelves) the weight of MDF boards is being continuously reduced.

The prediction of the strength and damage behaviour of these components is complicated due to the directional dependence of the mechanical material behaviour, which is why elaborate multi-scale simulations are necessary for precise predictions. In order to reduce the high computational times, we develop model reduction methods that determine the effective material behavior, such as fatigue and damage, using microstructure simulations with FeelMath.
