Cohesive Zone modellingI wanted a description of Cohesive Zone Modelling, one of the first papers I found was written by a PhD student (not sure if the paper was accepted or not) the report went in to some detail. It says it was invented by Dugdale(1960), Barenblatt (1962), Rice (1968) amongst others. From what I can gather it regards a fracture as an gradual process where separation takes place between two adjacent surfaces across am extended crack tip (cohesive zone) and is resisted by the presence of cohesive forces.
Cohesive forces: it is the force of attraction between the particles of the same substance
Unfortunately I got confused after this, so I came across this paper
