Compressive properties of Advanced Pore Morphology (APM) foam elements

Advanced Pore Morphology (APM) foam elements have a spherical outer skin and a porous inner structure. APM foam is a product of the improved powder metallurgy FOAMINAL® process. The present work investigates the mechanical properties of single APM foam elements under quasi-static and dynamic compressive loading. By means of μCT techniques, an accurate finite element model is generated. The compressive force-displacement response of APM foam elements is numerically evaluated for different diameters and strain rates. The results of the numerical analysis are compared with experimental data. Good agreement is found. Quasi-static and dynamic loading are both investigated by making use of numerical analysis and verified by comparison with experimental results.
