Influence of Cell Morphology on the Compressive Deformation Behavior of Aluminum Foams

Abstract:

Closed-cell aluminum foams with different morphology were fabricated under both increased and reduced pressure. It is shown that the cell size distribution and cell wall thickness is significantly influenced by foaming pressure. Quasi-static compressive tests were performed on foam specimens with similar density but different cellular structure. Results indicates that compressive stress of aluminum foams with homogenous structure is much higher than that of specimen with wide cell size distribution.
