Numerical Modelling and Validation of Mixed-Mode Fracture Tests to Adhesive Joints Using J-Integral Concepts

The interest in the design and numerical modelling of adhesively-bonded components structures for industrial application is increasing as a research topic. Although on joint failure under pure mode widespread, applied bonded joints are often subjected to mixed loading at crack tip, which more complex than affects strength. Failure these objective predictions through mathematical models, latter based Finite Element Method (FEM), using Cohesive Zone Modelling (CZM). Single leg bending (bending) testing among those employed study loading. This work aims validate FEM-CZM SLB joints. Thus, geometries used experimental were reproduced numerically experimentally obtained properties models. Upon validation technique, parametric involving cohesive laws’ parameters performed, identifying with most influence behaviour. As result, it was possible model tests adhesive estimate mixed-mode behaviour different adhesives, enables structures.
