“…Pitting or uniform corrosion is a dominant parameter for steel deterioration which can reduce the design life of a structure (5,6). The combination of fatigue loading and corrosion can cause a significant reduction in strength and stiffness, leading to accelerated failure of steel-composite structures (6)(7)(8)(9).…”

This paper outlines an experimental investigation into the durability of large-scale adhesively bonded joints with a thick layer of methyl methacrylate adhesive (MMA). Ageing has been performed by immersion in a 3.5 wt% NaCl solution for 10 weeks at 50°C. Two aged and one unaged specimen were subjected to tensile testing, and three aged and one unaged specimen were loaded up to ~3.5 million fatigue cycles followed by a residual tensile test. The ductility of the adhesive is affected by ageing and fatigue testing. Despite a decrease in ductility, the plastic zone development was adequate for the required strain redistribution without compromising the joint performance (strength and stiffness) demonstrating the fatigue tolerance of the joint. The shear, longitudinal, and peel strain values in the adhesive bulk are evaluated by digital image correlation. The shear strength values are significantly higher than the requirements following from the design. All specimens failed by sudden delamination of the composite plate. Post-mortem analysis showed no corrosion travel at the interface of steel and adhesive.

“…23–26 In addition to the experimental research on the effects of various factors such as temperature, 27 adhesive thickness, 28 vibration frequency, 29 and load ratio, 30 a large number of numerical studies have been carried out to predict the fatigue life of adhesive joints. 31–34 However, the function and applicability of some methods are limited and we cannot get accurate results. Since the propagation of small cracks under cyclic loading is a common failure mode in such components, life can be predicted according to the fatigue crack growth rate behavior in composites bonding.…”

Composite materials are widely used in the automobile industry, compared with traditional mechanical connection, in terms of efficiency and manufacture cost structure, adhesively-bonded joints are usually the material most appropriate connection technology. Adhesively-bonded joints have good performance under fatigue load and the stress concentration is smaller. Lack of reliable design methods, long-term aging behavior, and fatigue life assessment of the adhesive joint, which are limits the bonded joints technology popularization and application. In order to describe the crack propagation process more accurately, an improved generalized crack propagation model was proposed to predict the fatigue life of composite bonded parts. The crack propagation process is divided into three stages, and the influence of machining technology, residual stress, and actual temperature in the process of machining are considered. The model provides an effective theoretical basis for accurately predicting the residual life of composite bonded structures. Experimental and simulation results show that the proposed model expands the prediction range of the existing theoretical model, and the prediction accuracy is significantly improved.

To investigate the effect of alternate corrosion and fatigue on fatigue crack growth characterization of 2024-T4 aluminum alloy, the pure fatigue test, “corrosion + fatigue” test (commonly known as pre-corrosion fatigue), and the “fatigue + corrosion + fatigue” alternating test of single-sided notched specimen of 2024-T4 aluminum alloy were carried out. The fatigue crack life of alternate corrosion and fatigue is longer than that of the pre-corrosion fatigue when the corrosion time is the same. And the more the times of alternating, the longer the crack growth life will be. This is mainly because the fatigue crack growth rate will change suddenly, which will have a certain hysteresis effect on the fatigue crack growth. The corrosion and fracture morphology characteristics of the alternate test were examined by scanning electron microscopy (SEM), and the composition of corrosion products was examined by the energy dispersion spectrum (EDS). The prediction model of fatigue crack growth rate considering the alternating hysteresis effect of corrosion and fatigue based on the Paris formula was established, and the parameters and precision of the model were calculated and verified. The results show that the model has certain engineering application value.
