For an in-depth understanding of the failure of structural materials the study of the deformation mechanisms in the bulk is fundamental. In situ synchrotron radiation computed laminography provides 3D images of thin plates subsequently processed by digital volume correlation to measure displacement and strain fields by using the natural contrast of the material. Difficulties arise from the lack of data, which is intrinsic to laminography and leads to several artifacts, and the weak absorption contrast in the 3D image texture of the studied material. To lower uncertainty levels and to have a better mechanical admissibility of the measured displacement fields, a regularized digital volume correlation procedure is introduced and applied to analyze localized displacement and strain fields.
