21. Methods to Reduce the Size-of-Source Effect in Radiation Thermometers
Published: 4/1/2005
Authors: Howard W Yoon, David W Allen, Robert D. Saunders
http://www.nist.gov/manuscript-publication-search.cfm?pub_id=841848

22. Simultaneous Visible and Thermal Imaging of Metals During Machining
Published: 3/28/2005
Authors: Eric P Whitenton, Robert W Ivester, Howard W Yoon
Abstract: In order to investigate temperatures reached during orthogonal metal cutting, a novel approach for measuring temperatures at the tool-chip interface has been developed based on high-speed thermography. A thermal infrared camera and a visible camera ...

26. Influence of Heating Rate on Flow Stress in High-Speed Machining Processes
Published: 4/1/2004
Authors: Timothy J Burns, Robert W Ivester, Michael Kennedy, Richard L. Rhorer, Matthew A. Davies, Howard W Yoon, Lyle E Levine, Richard Joel Fields, D Basak, Eric P Whitenton
Abstract: For several decades, a major focus of machining research has been the measurement and prediction of temperature. Here, the influence of the rate of heating on the flow stress, and the implications of this for finite-element modeling of high speed me ...

27. Temperature Control of Pulse Heated Specimens in a Kolsky Bar Apparatus Using Microsecond Time-Resolved Pyrometry
Published: 3/1/2004
Authors: D Basak, Howard W Yoon, Richard L. Rhorer, Timothy J Burns, T Matsumoto
Abstract: Analysis of maching processes is important in the understanding and improving of manufacturing methods. The modeling of machining processes relies on high-strain-rate, high-temperature material properties. A split-Hopkinson (or Kolsky) bar has been ...
