LEPTOS S

LEPTOS S is an innovative, powerful and comprehensive module for the analysis of Residual Stresses measured by 0D, 1D or 2D detectors by use of classic sin²ψ and extended XRD² methods. The main LEPTOS S features are:

Five methods for finding a peak position: Gravity, Sliding Gravity, Parabolic, Pseudo-Voigt and Pearson VII
Comprehensive data correction capabilities: absorption, background subtraction, polarisation correction, smoothing and Kα₂-separation
User-extendable Material Data Base including elastic properties of materials and XEC
Calculation of the stress tensor in sample and principal coordinates for normal, normal & shear, biaxial, biaxial & shear, and triaxial stress models
Comparison of XRD² and sin²ψ methods by using an integration tool
Display of the ε_φψ (sin²ψ), d_φψ (sin²ψ) and 2_φψ (sin²ψ) regressions
Angular orientation matrix between main and sample’s coordinate systems
