Abstract

The local behaviour of a composite profile with annular cross-section is studied in presence of interfacial cohesive forces at the ends, where the lateral surface may be involved in a bonding connection. Features include the possibility of warping displacements, nonlinear shear strains within the thickness of the annular wall originated by the bonding interactions. Numerical simulations are carried out in order to investigate the tube behaviour over the loading path up to the failure, thus underlining the relevance of the thickness on the magnitude of the shear strains
