Experimental Investigations on the Energy Absorption of Aluminum TPMS Structures Under Dynamic Loading

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.
ABSTRACT Triply periodic minimal surfaces (TPMS) constitute a prominent class of cellular structures and have gained considerable attention in current research. These structures are genus‐infinite surfaces with zero mean curvature, which prevents self‐intersection. They also exhibit periodicity in all three spatial directions and exhibit enhanced multi‐
