Identification of Bodner-Partom Viscoplastic Model Parameters for Some Aluminum Alloys at Elevated Temperature
Abstract
The paper presents the identification process of inelastic (viscoplastic) properties for two aluminum alloys at a temperature of 120°C. The material parameters are calculated on the basis of uniaxial tension tests. Twelve tests at elevated temperature for each alloy have been performed—three tests for four different strain rates. The main purpose of the paper is to identify the Bodner-Partom viscoplastic model parameters for two aluminum alloys. The additional purpose of the research is the comparison of the parameter values at elevated temperatures for two types of aluminum alloys. The results have been successfully verified by numerical simulation of the laboratory tests.
