Hello,
I am trying to model an adhesive failure with an instantaneous failure, and the adhesive gets completely delaminated from both surfaces at the same moment. It seems not to fit into the cohesive zone model as there is no failure within the adhesive itself. There is a weld failure model, but I am trying to characterize analytically when the moment of failure for a modified model would happen, and the closest I can get right now is estimating the stress concentration at a failure load in the adhesive, and then extrapolating that to when I see a similar stress concentration in the modified model.
Thank you!
