When developing products, engineers face challenges in solving technical, economical, but also ecological conflicts of objectives. A common technical conflict is the contradictory behaviour between the stiffness and mass of components. A possibility to resolve this contradiction is offered by multimaterial components, which are made possible by a loadoptimised design. Taking the example of topology-optimised multi-material components, this article shows a method for taking the ecological impact of raw material extraction into account in selecting suitable designs by offsetting a performance index with the results of ecological impact assessment calculations. These results are analysed in order to identify a possible solution according to the technical-ecological conflict of objectives.

Keywords: topology optimization, environmental impact, life cycle assessment, tailored forming, light weight design
