DIFFRACplus STRESS

STRESS is a data acquisition and evaluation software for investigation of residual stresses.

  • Data acquisition in Omega mode: operation on a standard D5000, D5005, D4 or D8 with rotating sample stage. For uniaxial stress determination.
  • Data acquisition in Psi mode: operation on a D5000, D5005, or D8 equipped with an open Eulerian cradle or a 1/4-circle Eulerian Cradle. For determination of the complete stress tensor.
  • Exact determination of the d-spacing values using the center of gravity, the parabola method, or a Pseudo-Voigt fit
  • Linear and angular oscillation for reduction of coarse grain and texture effects
  • Correction of raw data: LPA, background, Ka2, and smoothing
  • Graphical display of all measured diffraction peaks with all applied corrections
  • Graphical display of strain, peak intensity, and peak width versus sin2Psi
  • Full compatibility with other DIFFRACplus programs for additional evaluations
  • Full documentation of measurement and evaluation parameters and results in report files with standard data structure for direct use in text editors
