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 ...
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 ...
In practice, thecohesive layersimulates the possible de-bonding between the plies of CFRP. The different height for the adhesive elastic layers for each adhesive was implemented after the one used for AF163-2k with satisfactory results was found to be underestimating the failure load for the XNR...

Fig. 13. Typical deformed shape of a steel beam at plate end debonding failure. 5.2.2. Interfacial stresses Unlike the analytical solution, the three-dimensional FE model produces interfacial stresses that vary not only along the length but also across the width of the beam. Representative contou...

An adhesive elasto-plastic contact model for the discrete element method with three dimensional non-spherical particles is proposed and investigated to achieve quantitative prediction of cohesive powder flowability. Simulations have been performed for uniaxial consolidation followed by unconfined compression to...
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. (C) 2016 The Authors...

A map of the count rate values correlates with microscopic photographs which also reveal adhesive vs. cohesive failure. The β ray and reflection techniques are conducive to automatic computerized mapping and averaging whereas the photographic technique is not....
