A new geometric correction factor for a finite width center cracked plate loaded by two pairs of splitting forces

X-ray diffraction data have to be corrected by geometrical correction factors prior to any quantitative analysis. Here the case of grazing incidence X-ray diffraction measurements is considered, including the case of high exit angles. First, an approach taking into account the evolution of the diffracting area during an ω scan is presented. From the calculation of the effective part of the sample surface that participates in the diffraction phenomena at each step of the scan, a more accurate correction factor than those commonly used is derived and the evolution of the line shape along a zero-width rod is explained. Secondly, the case of finite-width rods, under the point-like sample approximation, is considered: the influence of the partial integration, as a result of the detector in-plane acceptance, of a rod with an anisotropic in-plane shape, is studied and leads to an analytical expression for the corresponding correction factor. Finally, a full numerical simulation is presented, which provides an alternative method for correcting the experimental intensities and shows in which conditions the previous formulae are no longer valid.

Force Equilibrium

A general finite width correction ( FWC) factor is derived in this letter for an anisotropic laminate with elliptical soft/hard inclusion. Using the closed-form solutions for the stress components in the laminate, the derivation of the FWC factor is based on the concept of the global force equilibrium. Some specific cases are discussed. The accuracy of the derived FWC factor is demonstrated.

Wide Range

This paper presents results of calculation of the geometric correction factor β of the compact square-sectioned samples. It is shown by simulation that in compact samples thickness resonance type changes from longitudinal wave to Lamb wave. Furthermore, the geometric correction factor varies over a wide range and nonlinear in compact samples. The dispersion curve of the geometric correction factor β for compact square-sectioned samples is built.
