چکیده انگلیسی
The paper investigates the failure and behaviour of metal/composite double lap shear (DLS) joints where the composite is the inner/loaded adherend, using multi-scale modelling techniques. The unidirectional (UD) composite is based on glass fibre and vinyl ester resin moulded by pultrusion. The multi-scale models include a long overlap DLS joint (macro), small shear and tensile laminate joints (meso) and fibre-matrix resin models (micro). The macro- and meso-scale joints/models were mechanically tested and numerically analysed to determine failure loads and corresponding stresses and to identify the loci of failure within the joint interfaces. In addition, the numerical modelling was extended to include micro-scale models to determine transverse tensile stresses at the fibre-matrix interface to further understand failure and behaviour. The study concluded that the failure in the bonded composite is largely governed by the maximum transverse strength at the fibre-matrix interface and its defects. Also, it was concluded that this stress might be suppressed by the longitudinal tensile stress acting on the UD composite at the surface just below the bondline.
