Abstract

The aim of this work consists in developing a novel test rig, which is inspired by the Shear Torsion Bending (STB) rig designed for unidirectional composites. The test rig is capable to carry out fracture characterization tests on pre-delaminated composite sandwich specimens subjected to external out-of-plane shear loadings. Boundary conditions and specimen geometry have been designed in order to induce an out-of-plane stress state as uniform as possible along the debond front. Theoretical and numerical analyses of the specimen enable the understanding of how specimen geometrical parameters and loads introduction influence stress and energy release rate G distributions along the debond front.
