A mathematical analysis is made of data obtained by the dynamic x-ray diffraction technique. It is shown how by measuring the integrated diffraction intensity over a given interval of the strain cycle and accumulating results over many cycles of strain, the portion of the change in diffracted intensity which is in phase delta I and out of phase delta I with the applied sinusoidal strain may be obtained. The means for separating contributions of overlapping crystalline and amorphous peaks is discussed as is the determination of the dynamic orientation function by graphical integration of the change in diffracted intensity with azimuthal angle.
