Effect of Adding Graphene Oxide Nanoplatelets on the Araldite Adhesive Fracture Strength under Mixed-Mode I/II Loading
In the present paper, the effect of adding graphene on the fracture strength of the Araldite adhesive was studied. Experimental specimens were made of PMMA and then were bonded using a thin adhesive layer. Different loading modes were created by using the modified Arcan fixture. The effect of adding graphene to the adhesive layer was studied at four different weight ratios of graphene, including 0.00, 0.25, 0.50, and 1.00%. The results derived suggest that the experimental specimens with 0.5 wt % graphene have the highest fracture force. For specimens with the same amount of graphene, the highest fracture force was obtained under the mode II loading condition. The experimental results were compared with the results of the finite element model. The fracture behavior of an adhesive layer was modeled using the cohesive zone model. The maximum nominal stress criterion and the quadratic power law criterion were used for the crack initiation and propagation in the adhesive layer, respectively. The comparison between the numerical and experimental results shows overall good agreement.
期刊介绍：
The journal provides an international medium for the publication of theoretical and experimental studies and reviews related in the physical mesomechanics and also solid-state physics, mechanics, materials science, geodynamics, non-destructive testing and in a large number of other fields where the physical mesomechanics may be used extensively. Papers dealing with the processing, characterization, structure and physical properties and computational aspects of the mesomechanics of heterogeneous media, fracture mesomechanics, physical mesomechanics of materials, mesomechanics applications for geodynamics and tectonics, mesomechanics of smart materials and materials for electronics, non-destructive testing are viewed as suitable for publication.
