Abstract

Based on the Johnson-Cook material model, the deformation properties of metal ring under impact loading were numerically analyzed. Friction calibration curves under impact load were obtained and they were made comparison with the quasi-static results. The influence on calibration curves and critical coefficient of friction by different loading speeds and different strain rate sensitivity coefficient was illustrated. The calculation results showed that calibration curves under impact load had similar tendency but obvious difference in quantity with the quasi-static results. Both the strain rate effect and the inertia effect had influences on calibration curves when the ring specimen subjected to impact loading. The inertia effect played a major role, and the influence by the strain rate effect showed not very obvious. Furthermore, critical coefficient of friction existed during the ring compression and it can be considered as an intrinsic property of metal ring, which resulted from that it kept constant in different calculation conditions.
