TD-RSD X-ray Residual Stress Analyzer
Chinese version residual stress measurement and analysis software supports both linear and elliptical fitting methods. It employs complete stress equations without assuming zero shear stress, along with the elliptical fitting method, allowing simultaneous measurement of normal stress and shear stress values. Each measurement uses more than 9 ψ angles. Peak profile fitting includes Gaussian, Lorentzian, Pearson VII, parabolic, etc. Measurement results can simultaneously display normal stress values, shear stress values, as well as information such as peak intensity, integral width, and full width at half maximum (FWHM).

User-Friendly Software
Performs linear and elliptical fitting methods. Utilizing complete stress equations that do not assume zero shear stress, along with elliptical fitting, it measures both normal and shear stress values simultaneously, with each measurement employing over 14 ψ angles. Peak profile fitting includes Gaussian, Lorentzian, Pearson, parabolic, etc. Measurement results can simultaneously display normal and shear stress values, as well as information such as peak intensity, integral width, and full width at half maximum (FWHM).
