Abstract

Aluminum alloys are widely used as materials for machine components because they have excellent specific strengths. The strength reliability of components made of aluminum alloys is often evaluated by conducting finite element analysis (FEA). In particular, in order to evaluate the reliability of the components subjected to cyclic loading at high temperatures, the FEA should be conducted as an elastic–plastic–creep analysis, and the fatigue strength of the components should be estimated based on the analysis results. However, in order to conduct an elastic-plastic-creep FEA, the material constants used for the analysis must be estimated by conducting not only tensile tests but also long-time creep tests under at least three stress levels at several temperatures. This will become an obstacle to completing the design and development of the machine components in a short period. Therefore, the present paper proposes a method by which one can efficiently estimate the material constants for elastic–plastic–creep FEA by effectively using stored test data without conducting creep tests. The validity of the estimation method is discussed by conducting simulations of cyclic compression-tension loadings showing strain rate and temperature effects using an elastic-plastic-creep constitutive model with the estimated constants.
