Abstract:
Indentation testing is a popular method used to determinethe mechanical properties of materials. In this paper, finite elementsimulations are carried out for cone indentation of metallic foamswith 80 different material parameters. The numerical results combinedwith the dimensionless analysis method are used to establish therelationship between the cone indentation behavior and the elastoplasticmaterial parameters of metallic foams. Based upon the relationship, areverse analysis is developed so that the elastoplastic properties ofmetallic foams can be extracted from the cone indentation data.Obtained results show that the Young's modulus, yield strength, and plasticcompression coefficient of metallic foams can be unambiguously determined bythe developed reverse method. However, some supplement information is needed inorder to evaluate the densification strain.
