Strain rate dependent material behavior for dynamic loads

Strain rate dependent material behavior
© Fraunhofer EMI

The material and component behavior of additively manufactured materials is investigated. In particular, the strain rate dependent behavior is analyzed in dynamic experiments and simulations.

The objective is the development of material charts and simulation models able to forecast material behavior, as well as an enhanced understanding of correlations of process parameters and post-treatment of materials.

Dynamic experiments at testing machines and impact tests at accelerator facilities are conducted.

Dynamic experiments with bionically optimized components are conducted at a component crash system.

A scientific material analysis by means of microscopic investigations of metallographic specimens; CT and SEM investigations in the material laboratory support the modeling.

An evaluation concept expected to allow reliable statements concerning the behavior of additively manufactured components in service is developed.

The results shall be used for the development of application-specific design rules.
