|Title:||On Modeling the Peak Temperature on the Tool-Chip Interface during High-Speed Machining of AISI 1045 Steel|
|Published:||December 08, 2010|
|Abstract:||New experimental data on AISI 1045 steel from the NIST pulse-heated Kolsky Bar Laboratory is presented. The material is shown to exhibit a stiffer response to compressive loading when it has been rapidly preheated than it does when it has been heated using a slower preheating method to a testing temperature that is below the eutectoid temperature. Suggestions are made as to how to modify the well-known Johnson-Cook constitutive model of Jaspers and Dautzenberg for this material to achieve improved temperature predictions.|
