Stretching and debonding of adhesive fibril

KPKrupal PatelUniversity of Oxford MCMatteo Ciccotti EBE. BarthelCentre National de la Recherche Scientifique

Key Points

The aim is to understand the relationship between debonding force and displacement in adhesive fibrils based on fracture energy.
Analyzed debonding force and displacement characteristics of adhesive fibrils PSA 6A and PSA 6B.
Derived power law relationships using fracture energy.
Examined the effect of varying forces and displacements on adhesive performance.
Debonding force exhibited a power law dependency on displacement for both PSA types.
Fracture energy influenced the debonding behaviour differently in PSA 6A and PSA 6B.
Stronger correlations were observed between debonding force and displacement compared to previous models.

Abstract

(a) Debonding force: F c ∝ d x, x = m for PSA 6A, p for PSA 6B (b) Debonding displacement: δ c ∝ d y, y = n for PSA 6A, q for PSA 6B, where x and y are function of fracture energy used to derive the power law.
