ISODEC: Software for Calculating Diffraction Elastic Constants

June 1, 2012
Author(s)
Thomas H. Gnaeupel-Herold
A program is introduced that calculates diffraction elastic constants for the models according to Reuss, Hill, Kröner and inverse Kröner. For materials with preferred orientation it uses the orientation distribution function (ODF) to calculate the

A Model for Calculating Diffraction Elastic Constants

January 18, 2012
Author(s)
Thomas H. Gnaeupel-Herold, Adam A. Creuziger, Mark A. Iadicola
An alternate model is proposed to calculate the diffraction elastic constants from the elastic constants of the single crystal. It is based on the inverse elastic susceptibility and thus it is related to the elastic polarization approach widely known as

Diffraction study of the retained austenite content in TRIP steels

January 19, 2011
Author(s)
Thomas H. Gnaupel-Herold, Adam Abel Creuziger
The results of a study of using neutron diffraction for determining the retained austenite content of TRIP steels are presented. The study covers a wide area of materials, deformation modes (uniaxial, biaxial and plane strain), strains, and the retained

Robustness of the Sheet Metal Springback Cup Test

October 16, 2008
Author(s)
Timothy J. Foecke, Thomas H. Gnaupel-Herold
The robustness of a proposed test for elastic springback characterization of sheet metal has been examined using a matrix of defined experimental errors. A series of flat bottom deep drawn cups made from AISI 1010 steel sheet were examined. It was found
