Latest results for elasto-plastic identification at high rates using inertial impact

The behavior and failure mechanisms of materials often change at high strain rates when compared with their quasi-static response. In automotive manufacturing the use of aluminum alloys has doubled in the last decade as the introduction of aluminum frames can reduce the body weight. During crash events these aluminum alloys can reach strain rates of 104 s−1 [1] and understanding their dynamic response is necessary to design safe vehicles. In this paper, inertial impact tests coupled with ultra-high speed imaging and the virtual fields method were used to identify the high strain rate elasto-plastic properties of Al6082-T6.

Abstract

The behavior and failure mechanisms of materials often change at high strain rates when compared with their quasi-static response. In automotive manufacturing the use of aluminum alloys has doubled in the last decade as the introduction of aluminum frames can reduce the body weight. During crash events these aluminum alloys can reach strain rates of 104 s−1 [1] and understanding their dynamic response is necessary to design safe vehicles. In this paper, inertial impact tests coupled with ultra-high speed imaging and the virtual fields method were used to identify the high strain rate elasto-plastic properties of Al6082-T6.
