Abstract
Generally in mechanics, 3D problems can be analysed from simulations by finite elements and the results can be compared with the measurements obtained on the surface of the specimen. However, in the case of structures with complex geometries or specific loads, it can be necessary to determine experimentally the 3D strain field to validate the numerical approach in the whole volume. We present two techniques we have developed to observe 3D mechanical effects at the core of a specimen: the scattered light photoelasticity and the optical scanning tomography coupled to Digital Volume Correlation (DVC). The aim of this work is to determine the limitations, advantages and drawbacks of both methods and allows us to choose the well-adapted technique at each study.
