Strain rate dependent material behavior for dynamic loads in car crash

Additively manufactured materials are analyzed in experiment and simulation. In particular, the strain rate dependence of the material behavior is investigated which is of high relevance for special load cases like car crash.

Making quality visible

To improve the reliability and shape accuracy of all additively manufactured products, we develop individual safety systems for your entire product development process:

  • Products and processes - reproducible processes & dimensionally accurate products
  • Quality management in the production chain - reliability & shape accuracy

The Fraunhofer Competence Field Additive Manufacturing supports you with its many years of cross-industry knowledge in the integration of quality assurance tools and in the development and optimization of your quality management system.

Products and processes

Computer simulation and the technologies of additive manufacturing are becoming increasingly important in industrial product development due to their potential for cost and time savings. Even before a product, for example a newly developed machine component, is actually manufactured, the manufacturing process can optimize the entire development process. In a further step, additive manufacturing can be used to produce first prototypes, small series or tool inserts for various manufacturing processes quickly and cost-effectively. In addition to the simulation, a complete component verification or optimization is also possible.

Reliability and shape accuracy of the products

Manufacturing processes shape the application behavior and reliability of components. Volume changes of the material during processing, for example shrinkage during the polymerization of a stereolithography resin or during the sintering of powders, can lead to distortions in shape, internal stresses and in the worst case even to the formation of cracks. The simulation of manufacturing steps contributes to the understanding of the relationship between process parameters and component properties. Experimental methods such as the incremental borehole method or X-ray diffraction are used to analyze residual stresses.
