WebApr 14, 2024 · The CZM is based on elastic material behavior. Since the adhesive used in the study has a ductile behavior, the behavior of the non-linear plastic material properties should be reflected in the analysis as well as the elastic material behavior of the adhesive. WebWith no limitations of deformation from the cohesive elements, the surface-based cohesive behavior is typically more prone to define and allows simulation in a wider range of cohesive interactions, such as two “sticky” surfaces coming into contact during the analysis. Such numerical implementations are well described in many existing papers.

WebHowever, surface-based cohesive behavior is typically easier to define and allows simulation of a wider range of cohesive interactions, such as two “sticky” surfaces coming into contact during an analysis.
