National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Proportion of Plastic Work Converted to Heat in T16AL4V: MTS Model Prediction and Experimental Data.

PB2001105675

Publication Date	2001
Personal Author	Macdougall, D. A. S.; Maudlin, P. J.
Page Count	10
Abstract	The conversion rate of plastic work to heat, F, is an important quantity. It is necessary in finite element simulations involving plasticity in which temperature calculations are made. In this paper, the Mechanical Threshold Stress (MTS) model is compared to experimental measurements of the variation of with plastic strain for Ti-6Al-4V. The experiment was performed in high-speed torsion with the surface temperature measured using radiometry.
