Abstract. In this paper we study the asymptotic behavior of a structure made of curved rods of thickness 2δ when δ→0. This study is carried on within the frame of linear elasticity by using the unfolding method. It is based on several decompositions of the structure displacements and on the passing to the limit in fixed domains. We show that any displacement of a structure is the sum of an elem...

The applicability of residual stress analysis is expanded to the full 2theta range, particularly to lower diffraction angles (2θ<<120), in order to be able to analyze residual stress in complex samples. For reliable results it is crucial that systematic errors are absent. The systematic errors considered in this paper are alignment errors like specimen displacement and incident beam misalignmen...
