Bondline thickness: Fracture mechanics perspective

The bondline thickness is a crucial parameter affecting the strength and toughness of adhesive joints. This parameter is responsible for the stress distribution, and thus, the efficiency of the stress transfer between the adherends, the failure modes, and the correspondent failure loads. However, the available literature reports different...

On the influence of the adhesive and the adherend ductility on mode I fracture characterization of thick adhesively-bonded joints

Thicker bondlines along with manufacturing-tolerant and fracture-resistant adhesives are trends visible across different industries, especially maritime. In this work, two contrasting adhesives: an elastic-brittle epoxy-based, and a nonlinear-ductile methyl methacrylate (MMA) are characterized and compared via tensile, compact tension (CT)...
