摘要

For the characteristics of soft X-ray stress testing technology, a formula to resolve main residual stress is deduced based on analyzing the relationship between main residual stress and normal stress of different sections. The distribution of main stress of laser shock forming TA2 metal sheet is studied combined with the experimental study on the determining residual stress with soft X ray diffraction analyzer. The result shows that testing and calculating main residual stress is an important approach to study the deformation law of sheet metal material.
