AZ31 Magnesium Alloy Parameters Identification through Inverse Analysis at 713 Κ

摘要

This paper introduces a fast and accurate procedure for determining the constants of magnesium AZ31 alloy at 713 K. The material behaviour is modelled by means of the power law relationship between the equivalent flow stress, the equivalent strain and the equivalent strain-rate within a narrow equivalent strain-rate range. The material constants, m, n and Κ were obtained in the power law relationship by means of constant pressure bulging tests coupled with the use of an inverse analysis technique.
