Splet05. feb. 2013 · One of the fundamental aspects in cohesive zone modeling is the definition of the traction-separation relationship across fracture surfaces, which approximates the nonlinear fracture process. Cohesive traction-separation relationships may be classified as either nonpotential-based models or potential-based models. SpletThis is the subject of general continuum mechanics. It depends largely on the geometry of the bodies and on their ( constitutive) material behavior (e.g. elastic vs. plastic response, homogeneous vs. layered structure etc.). Secondly, there is the overall motion of the bodies relative to each other.
