Residual Stress Analysis

X'Pert Stress provides:

Instant recalculation of all results upon changing a parameter.

Classical uni-axial and bi-axial sin^2(Y) residual stress analysis.

Database of 400 elastic constants and a built-in X-ray Elastic Constants (XEC) calculator.

9 different methods for exact peak position determination.

Unique routine to evaluate and correct minor misalignments.

Note:
Both measurement types known as Y-stress and W-stress variant are covered.

Peak position determination can be performed using:

Center of gravity

Sliding center of gravity

Parabola fit

Gauss function fit

Lorentz function fit

Pearson VII function fit

Middle at % height

Manual position

Cross-correlation function

Data retrieval is possible for:

Isotropic elastic constants (E and n)

X-ray elastic constants (s1, 1/2s2)

Single crystal elastic constants (s11, s12, s44, c11, c12, ...)
