“…Other contributions include those of Jablonski [39] and of Brussat and co-workers [40,41]. These works included the application of the Paris relation to various adhesive systems as well as early investigations of the effect of mode mixture, indicating that the total SERR provided a better correlation to the delamination growth rate than the individual mode SERR.…”

“…Of this equation Brussat et al already noted ''The equation is strictly empirical, and its form is subject to change in the future as a variety of mixed mode fatigue crack growth data becomes available [40]." Mall et al found that G tot = G I + G II was best at correlating the delamination growth in the bonded FRP specimens they studied [31].…”

An overview is given of the development of methods for the prediction of fatigue driven delamination growth over the past 40 years. Four categories of methods are identified: stress/strain-based models, fracture mechanics based models, cohesive-zone models, and models using the extended finite element method. It is highlighted that most models are phenomenological, based on the observed macro-scale behaviour of test specimens. It is suggested that a more physics based approach, focusing on elucidating the mechanisms involved, is needed to come to a full understanding of the problem of delamination growth.

The characterization of mixed-mode fracture toughness and fatigue delamination growth in fibrereinforced composites is crucial for assessing the integrity of structural elements in service. An asymmetric cut-ply coupon (ACP) loaded in four-point bending is here proposed to carry out the aforementioned characterisations. Analytical expressions of the energy release rate and mode-mixity for the ACP are derived and validated by means of finite element analysis. A fracture toughness and fatigue characterisation of the carbon/epoxy material IM7/8552 is carried out via ACP specimens. It is proved that the material data obtained from ACP specimens match those generated using ASTM standard mixed-mode bending (MMB) coupons. The main reason for the introduction of the ACP test resides in its applicability to characterisation scenarios where measuring the delamination length with optical means, as required for MMB coupons, is difficult. Such scenarios include the investigation of static and fatigue delamination growth at low and high temperatures, which requires the usage of environmental chambers. This poses significant constraints in terms of volume available for the test rigs, and, most importantly, limitations on visual access to observe delamination propagation.However, the manufacturing of ACP coupons is more complex than for MMB specimens and the testing requires several additional precautions that are here discussed in detail.

“…This is commonly referred to as cyclic debonding. Basic concepts from fracture mechanics have proven successful in modeling cyclic debonding (1)(2)(3)(4). In a previous study (5) by Mall et al, cycli~ debonding of adhesively bo~ded composite joints was investigated with the cracked-lapshear (CLS) specimen.…”

A combined experimental and analytical investigation of an adhesively bonded composite joint was conducted to characterize the fracture mode dependence of cyclic debonding. The system studied consisted of graphite/epoxy adherends bonded with EC 3445 adhesive. Several types of specimens were tested which provided the cyclic debond growth rate measurements under various load conditions: mode I, mixed mode I-II, and almost mode II. This study showed that the total strainenergy-release rate was the governing factor for cyclic debonding.
