Residual Stress and Diffraction Elastic Constants Measurements with a Personal Computer

Abstract

Software is described for the measurement of residual stresses and x- ray elastic constants on a diffractometer under computer control. The computer and interfaces to the hardware are relatively inexpensive and may be set up with only moderate electronic and programming expertise. Both biaxial and triaxial stress measurements may be made to an operator specified error. Measurements of the x-ray elastic constants may also be made to a pre-specified error. Additionally, programs for use data collection are described which allow the data to be processed separately at a later time. (jes)
