In all the cases studied, the numerical analysis correctly predicts the driving mechanisms and the specimens' final failure. Accurate fatigue life predictions are made with the addition of a Paris based damage law to the interface elements used to model the adhesive failure....
Highly paraffinic (or waxy) crude oil can cause significant problems in subsea pipelines due to wax-oil gel blockage resulting from the precipitation of the wa

Using the model system hydrogenated diamond-like carbon (a-C:H) on titanium (Ti) substrates the effect of a changing film thickness on the cohesive and adhesive failure of hard and brittle films on ductile metallic substrates is analyzed by uniaxial loading. A film thickness size effect has be...
In the first part of this section the cohesive failure is discussed while the second part focuses on the adhesive failure. Discussion Upon uniaxial loading elastic–plastic deformation of the Ti substrate affects the stress generation in the a-C:H film. In the elastic region the substrate deform...
The convergence behaviour of the model is improved. The numerical efficiency is high and enables a representation of both cohesive failure of the adhesive and delamination failure on a structural level. 展开 关键词: Bonded joints Delamination Finite elements Cohesive zone modelling Model reduction ...
In this work, Cohesive Zone Modelling (CZM) was used to simulate failure of T-peel bonded joints with 1.5mm thick adherends, respectively, bonded toghether with Loctite Multibond 330 adhesive. The fracture toughness and load-opening behaviour recorded in previous experiments on bonded Double ...
Cohesive failure in the epoxy adhesive layers of carbon-fiber-reinforced plastic (CFRP) joints is incomprehensible because the adhesion interface with almost no covalent bonds is supposed to be the weakest in the joined structure. It is a long-standing unsolved issue that adhesive failure at the ...
Analysis of Failure in Adhesively Bonded Joints Using Traction Separation Theory The analysis showed that: (1) The adhesive joint behaves linearly before the first cohesive element failure and after that the failure continues to ... G Ranjan,RK Pandey,AG Barman - 《Applied Mechanics & Materials》...
Cohesive interface elements are becoming a popular choice in the analysis of composite material failure, particularly for delamination. Use of such elements is not without pitfalls, which include the correct selection of material parameters and mesh size. This chapter gives an introduction to the use...
