Abstract

This paper presents a method of implementing dynamic material properties obtained through pulse-heated Kolsky Bar (Split-Hopkinson Bar) experimentation into commercially available finite-element simulation software. Material property data collected at high strain-rates and high initial temperatures provide a closer approximation to the conditions experienced during metal cutting than could be achieved with traditional material property testing. First, software used for cutting simulations simulates Kolsky Bar experiments. These simulations allow adjustment of the material model parameters to bring experimental and simulated true-stress true-strain curves into agreement. Finally, results from 2D orthogonal cutting simulations are compared to measurements made using a dual-spectrum high-speed microvideography system observing orthogonal cutting of a disk.
