摘要：

The anisotropic behavior of terra cotta ceramics is due to the lamellate structure of clay and to the extrusion forming process. In the case of low strains, this behavior is elastic. Digital image correlation was used to give strain field measurements. These measurements allowed to locally characterize transverse isotropic elastic behavior. The consistency of the local characterization procedure is showed by comparing kinematic field measurements on small specimens with fields obtained by 3D finite element Computations.
