Abstract

Abstract

Indentation responses and deformation characteristics of closed-cell aluminum foams under elevated temperatures were experimentally investigated by using a flat-ended punch (FEP) and a hemispherical-ended punch (SEP). Based on the quasi-static experimental results at elevated temperatures, dimensional analysis and finite element simulations are used to examine the empirical relations of the SEP and FEP indentation load responses and the indentation depth and test temperature. The theoretical predictions based on the results of the analysis are compared with the experiments. It was found that the load responses are described well by the empirical formulas for different indenters at different temperatures. This provides the basis for applying a simple indentation test to investigate the mechanical properties of metallic foams.
