New Generation X-Ray Stress Measurement Using Debye Ring Image Data by Two-Dimensional Detection

Abstract

Measuring theory of two types of X-ray stress analysis method was compared with each other. One is the conventional method, in which zero-or one-dimensional detector is used for obtaining diffracted beam and stress is determined using the standard sin2ψ method. Another is the new type of X-ray stress analysis method, in which two-dimensional detector is used to obtain whole Debye ring and stress is determined using the cosα method. An experiment was conducted to investigate the validity.
