Layer Removal Residual Stress Determination function

The iterative evaluation method for the correction of residual stress measurement by X-ray diffraction on cylindrical specimens.

LRRSD stands for Layer Removal Residual Stress Determination

S_real = LRRSD(R,S,Rm,type)

R - is a vector. Use here values of the measurement points radii sorted in descending order. The last radius point is for the last point truly measured.

S - is a vector. Use here values of the measured residual stress for previously specified radii.

Rm - is scalar. It is the inner radius of the cylinder specimen. If cylinder specimen is without a hole, use Rm = 0.

type - is a string. Use "ax" for axial/longitudinal residual stress or use "tg" for tangential/transversal residual stress determination.
