Dispersion by cohesive failure occurs when hydrodynamic forces are sufficient to induce the removal of unilfiltrated fragments from the parent agglomerate or the breakage of wetted fragments from an infiltrated portion of the parent agglomerate. Adhesive failure is characterized by a breakage at the ...

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...
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 zone modelingIn 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...
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 ...
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 ...
content up to 7% (w/v), suggesting a change in the equilibrium between the cohesiveness and adhesion of the GOVM-gel adhesive, which may be attributed to the cohesive or adhesive failure of the glue itself or a mixture of causes, indicating failure of the adhesive-tissue interface [14]. ...
In adhesive bonds, this type of fracture is known as cohesive failure: when a layer of adhesive remains on both adherends. Adhesive failure is when fracture of failure occurs at the adhesive-to-adherend interface. Many American Society for Testing Material (ASTM) prescribe reporting the mode ...
