| Popis: | This work is dedicated to the experimental study of the shear properties of three-dimensional reinforced composites taking into account their structural features, in Iosipescu tests. Shear strains have been determined using Vic-3D non-contact three-dimensional digital optical system. The evolution of inhomogeneous strain fields on the surface of composite specimens of the structure under study has been analyzed. The variants of strain averaging in the specimen working area have been analyzed using Vic-3D tools. AMSY-6 acoustic emission system has been used to assess the structural integrity of composite materials under loading. |
