Simulative Determination of Effective Mechanical Properties for Digitally Generated Foam Geometries

Metal foams constitute a promising and emerging material class in the context of lightweight construction. There exists variety different foam topologies, on which resulting mechanical properties depend. To maximize potential use under load, present work addresses question how geometrical parameters influence behaviour. Therefore, an algorithm for digital generation design open pore structures is presented, that allows to regulate geometry precisely. A method retrieving effective from numerical simulations compression tests elastic regime introduced. Additionally, representativeness volumes considered investigated. This yields fully workflow, enables investigation properties. approach used conduct simulation studies generated with systematic variation parameters. Herein, range Young's moduli varying by up factor 1.3 at same porosity found. shows significant impact metal foams. The presented methodology insights, can guide optimization materials specific applications.
