“…Under pure-mode loading, damage onset occurs when the cohesive strength in tension or shear (t n 0 or t s 0 , respectively) is attained, i.e., the material's elastic ceases to exist and degradation begin (Sane et al 2018). Moreover, the crack proliferates up to the adjacent pair of nodes when the values of current tensile or shear cohesive stresses (t n or t s , respectively) become null.…”

Honey; It is a sweet product created by bees by collecting plant nectar and changing its content in their bodies, then taking its final form with maturation in the honeycomb. Apis mellifera, one of the insects of the genus Apis, known as honey bees, is responsible for producing most of the honey consumed worldwide. Since the bees use various plant nectars as raw materials, the variety of honey is very high, and technically, no honey is precisely the same as the other. It can be said that the most important reason for this is that honey is obtained from different plants by being exposed to different climatic conditions. Honey is a significant functional food that people have consumed since the hunter-gatherer periods due to its nutritional content and positive effects on health. Research has shown that beekeeping has been practiced in Anatolia since the Hittites. Flower honey produced in Anzer Plateau is one of the market's most popular and expensive honey. In this study, studies on Anzer honey, the first product with a geographical indication in Rize, where important honey producers are located in Turkey, the second largest honey producer in the world, will be compiled.

“…To corroborate these assumptions, accurate predictions in SLJ were found for the three adhesives. For this model, under pure-mode loading, damage initiation occurs when t n 0 or t s 0 are attained, i.e., the material's elastic behaviour is cancelled and degradation starts. 38 Furthermore, the crack propagates up to the adjacent pair of nodes when t n or t s become null. Under mixed-mode loading, stress and/or energetic criteria are often used to combine the pure-mode laws, and damage begins when the mixed mode cohesive strength ( t m 0 ) is reached.…”

The use of tubular adhesive joints has considerably grown, including applications in truss/vehicles frames and fluid transportation pipelines, but the impact performance of these joints is under addressed in the literature. It thus becomes pertinent to propose modelling techniques to predict and characterize tubular joints to withstand these loads, which involve a higher modelling complexity than the static loading case. This work evaluates, by cohesive zone modelling (CZM), the tensile impact strength of tubular joints between AW6082-T651 aluminium alloy adherends and bonded with different adhesives. Initially, CZM validation was accomplished with single-lap joint (SLJ) data. For the tubular joints, the influence of geometric parameters was evaluated by changing the overlap length ( LO) and outer tube thickness ( tSE). The analysis begins with an elastic stress analysis to the adhesive layer, followed by maximum load ( Pm) and dissipated energy at failure ( U) predictions using CZM, impact velocity effect and comparison with static analytical solutions. With this study, it was possible to evaluate the different geometrical parameters, select the optimal geometry and adhesive type, and to validate the CZM technique for the impact strength prediction of tubular adhesive joints.

The use of adhesive bonds has attracted considerable interest from the scientific community. Stepped-lap joints have the advantage of decreasing stress gradients along the bond length, although the outer steps still encounter stress levels above the steps in the inner zone of the joint. One possible way to reduce this stress gradient is to combine this type of joint with the use of two adhesives. This work consists of an experimental and numerical evaluation of stepped-lap dual-adhesive joints between aluminum adherends, for various overlap lengths ( LO), and comparison with stepped-lap single-adhesive joints. The adhesives Araldite® AV138, Araldite® 2015, and Sikaforce® 7752 were evaluated. Numerically, cohesive zone models with a triangular damage law were applied in the joint behavior prediction. The analysis of the results is presented in the form of failure modes, stress analysis, damage variable analysis, load–displacement ( P–δ) curves and maximum load ( Pm), and energy required to failure ( U). It was concluded that, in general, cohesive zone model presented precise predictions. In general, no significant increase in strength was achieved with dual-adhesive joint but, on the other hand, significant energy increases were obtained.
