WebThe measured adhesion (or cohesion) force F ad (or F c ) is related to the adhesion (or cohesion) energy per unit area by W ad = F ad /2π R for rigid surfaces with weak adhesive interactions, and by W ad = F ad /1.5π R (used in this study) for soft deformable surfaces with strong adhesion or cohesion. WebIn their proposed approach, the cohesive force and work of adhesive peeling are scaled cubically in the coarse-grained system. Sakai et al. (2012) developed a coarse-grained model to model the cohesive particles by quadratic scaling of the Van der Waals force. In their model, although the inter-surface distance of the particles depends on the ...
