Application a direct/cohesive zone method for the evaluation of scarf adhesive joints
With the increasing use of structures with adhesive bonds at the industrial level, several authors in the last decades have been conducting studies concerning the behaviour and strength of adhesive joints.

description | With the increasing use of structures with adhesive bonds at the industrial level, several authors in the last decades have been conducting studies concerning the behaviour and strength of adhesive joints. Between the available strength prediction methods, cohesive zone models, which have shown good results, are particularly relevant. This work consists of a validation of cohesive laws in traction and shear, estimated by the application of the direct method, in the strength prediction of joints under a mixed-mode loading. In this context, scarf joints with different scarf angles (
α
) and adhesives of different ductility were tested. Pure-mode cohesive laws served as the basis for the creation of simplified triangular, trapezoidal and exponential laws for all adhesives. Their validation was accomplished by comparing the numerical maximum load (
P
m
) predictions with the experimental results. An analysis of peel (
σ
) and shear (
τ
) stresses in the adhesive layer was also performed to understand the influence of stresses on
P
m
. The use of the direct method allowed obtaining very precise
P
m
predictions. For the geometric and material conditions considered, this study has led to the conclusion that no significant
P
m
errors are incurred by the choice of a less appropriate law or by uncoupling the loading modes. |
