Composites in biaxial cruciform tests: effect of geometry on volumetric strain evolution using X-ray computed tomography and digital volume correlation
Abstract Accurately characterising deformation in fibre-reinforced composites requires specimen geometries that both promote failure within the gauge zone and enable high-quality full-field strain measurements. These demands become even more critical under biaxial loading, where interacting stress states make it challenging to maintain stable and interpretable deformation in the specimen centre. This study systematically evaluates five […]
