WELCOME

Welcome to BEARTEX, the Berkeley Texture Package! BEARTEX provides a set of 24 programs running under the Windows environment to analyse preferred orientation in polycrystalline materials. The system is designed for users who are not texture theoreticians but need quantitative texture data for their applications. BEARTEX is independent of x-ray hardware and many programs can also be used to process neutron diffraction data.

It was developed for our own research needs over many years by Siegfried Matthies, Hans-Rudolf Wenk and John Donovan with significant contributions from Galina Vinel, Florian Heidelbach and Alene Pearson. We acknowledge contributions from the former Texture School of the ZfK Rossendorf, Dresden, Los Alamos National Laboratory, the University of Metz (France) and input and support from the Laboratoire de Cristallographie, Grenoble, particularly the help of Daniel Chateigner and Patrick Juen.

For now, it is assumed that the user is familiar with the basic concepts of texture analysis and has studied the introductory Literature
(e.g. Wenk, 1985 and Kocks et al., 1997) that explains such terms as pole figures (and how they are measured), orientation (defined by three Euler angles which represent rotations to bring crystal and sample coordinate system to coincidence), orientation distribution function (derived from measured pole figures) etc.
If you would like to know more about Quantitative Texture Analysis, a full QTA Internet course is available Here.

BEARTEX is not a substitute for POPLA the Preferred Orientation Package Los Alamos. POPLA has many more options which are not included in BEARTEX: We do not use the harmonic method, BEARTEX does not work on XT and AT personal computers. Several events made it necessary to go beyond the scope of POPLA. For our applications we often needed large numbers of pole figures and low crystal symmetries which has become easy to incorporate on PC processors with extended memory (386, 486 or 586) and programs can be assembled in a windows environment (WINDOWS version 3.1, 95 or NT).

The user friendly interactive environment, the range of sample and specimen symmetries is intended to make quantitative texture analysis fun for metallurgists, ceramicists, polymer scientists and geologists. Any comments about deficiencies and suggestions for future improvements are highly appreciated: Beartex. And now ...
