Fatigue/fracture characterization of composite bonded joints under mode I, mode II and mixed-mode I + II

Experimental and numerical studies of the fatigue/fracture behavior of carbon–epoxy composite bonded joints under pure mode I, pure mode II and mixed-mode I + II loading were performed. The Double Cantilever Beam, End-Notched Flexure and Single-Leg Bending tests were used for fatigue/fracture characterization under high-cycle fatigue loading. Equivalent crack length based procedures were used to evaluate the evolution of strain energy release...
