“…Some works also investigated qualitatively the damages induced in carbon fibre reinforced plastic (CFRP) bolted joint composites. In a study by Kapidzic et al, two-bolt, double-lap joints with quasi-isotropic carbon/epoxy composite specimens were subjected to uniaxial and biaxial cyclic loading at 90 °C [ 66 ]. The constant amplitude load was applied in force control with a sinusoidal wave shape, but the maximum applied cyclic load was well below the static load failure.…”

“…Therefore, all the damages were attributed to fatigue. A microscopy study of the bearing plane revealed that the main fatigue driving mechanisms were matrix cracking and fibre–matrix debonding [ 66 ]. Smith and Pascoe [ 67 ] found out that the damage induced in 0/90° ply CFRP composite with bolted induced by fatigue were: shear cracking in 0° plies, tensile cracking in 90° plies, interlaminar cracking.…”

As the fibre reinforced plastic composites gain larger and larger share in industry, the problem of joining them with metal elements becomes significant. The current paper is the first part of the literature review, which gathers and evaluates knowledge about methods suitable for mechanical joining of composite and metal elements. This paper concerns bolted joining, because this method of mechanical joining is widely used for joining composite materials. The paper describes failure modes of bolted joints in composite materials, the influence of the bolt clamping torque, the clearance between the bolt and the hole and aging on the performance of the joint, drilling techniques used in composite materials in order to minimize damages, different fastener types, inspection techniques, and finally, the techniques that have been developed in order to improve the strength of the bolted joints in composites. Since the hole drilled in a composite material in order to perform bolted joining is a weak point of the structure, those techniques: bonded inserts, titanium foil internal inserts, fibre steering, additional reinforcement, and moulded holes, mainly aim to improve the strength of the hole in the composite. The techniques have been discussed in details and compared with each other in the summary section.

“…These studies mainly focused on the fatigue life of the joints and only several of them qualitatively evaluated fatigue damage evolution and failure mechanisms of the joints through the limited measurement techniques, such as the strain gauge and extensometer method [2], the DIC method [3] and the infrared thermography [5,8]. In order to deeply explore the fatigue damage propagation and reveal the fatigue damage mechanism of composite mechanical joints, the numerical simulation techniques have been developed since the late 1980s [10][11][12][13][14][15][16][17][18]. Initially, a critical element model [10][11] was presented to predict fatigue behavior of composite hole laminates.…”

“…In order to overcome the deficiencies of the macro theories in aforementioned PFDM-type models, the micro-mechanics of failure (MMF) theory was extended to predict progressive fatigue failure of composite bolted joints [16], in which numerous fatigue tests of unidirectional laminates are required to obtain MMF critical parameters. Furthermore, to minimize the need for experimental material characterization, a model based on the kinetic theory of fracture for polymer matrices was developed to predict fatigue bearing failure of the hole laminates under the assumption that the initiation of the fatigue damage takes place in the matrix [17][18].…”

A residual strain model was presented based on the fatigue-accumulated damage mechanisms of composite materials. By combining the proposed residual strain model with a residual stiffness model, the gradually degraded material properties due to the damage in fatigue cycles were characterized. Accompanying the residual strain based gradual material degradation model with a micromechanics-based sudden material degradation rule for describing the stiffness degradation in one fatigue cycle and an extended maximum strain criterion for evaluating failure of materials, a progressive fatigue damage model (PFDM) of a typical double-lap three-bolt joint made of T800 carbon/epoxy composites was developed. Compared with the residual strength model in a traditional PFDM, the residual strain model has consistent parameters with those in the residual stiffness model, which could be determined by nondestructive experiments. Fatigue tests of the double-lap three-bolt joint specimens under a stress ratio R=-0.2 and three-level load ratios q=0.7, 0.8, 0.9 were performed. Good consistency between the experimental results and numerical predictions of the PFDM validates the efficiency of the proposed residual strain model and PFDM in accurately predicting the residual strength and fatigue life of composite structures.
