Micromechanics of flat-probe adhesion tests of soft viscoelastic polymer films

Thin Film Composite Silicon Elastomers for Cell Culture and Skin Applications: Manufacturing and Characterization

“…Our results are in line with published data, showing that a decrease of film thickness lead to an increase of the pull-off stress as the confinement, i.e. , the ratio between substrate diameter and film thickness, increases 38 39 . Based on these results and the data depicted in Figure 7 , we conclude that composite films with a total thickness of approx.…”

Bulk and Interfacial Contributions to the Debonding Mechanisms of Soft Adhesives: Extension to Large Strains

“…If the value of G o increases more rapidly with the debonding rate than the elastic modulus, transitions between different debonding mechanisms will be observed as the debonding rate is varied. 12 This qualitative description is in agreement with recent experiments. 6 Finally it is important to point out the relevance of our work to the much more common geometry of peel.…”

“…The rate dependencies of 𝒢 o and E can be quite different, giving a value of our control parameter 𝒢 o / E that depends on the debonding rate and temperature for a given substrate/adhesive combination. If the value of 𝒢 o increases more rapidly with the debonding rate than the elastic modulus, transitions between different debonding mechanisms will be observed as the debonding rate is varied . This qualitative description is in agreement with recent experiments …”

Thin Film Composite Silicon Elastomers for Cell Culture and Skin Applications: Manufacturing and Characterization

“…The adhesive properties of composite films exhibiting different film thicknesses of the soft skin adhesive were determined (Figure 7). Our results are in line with published data, showing that a decrease of film thickness lead to an increase of the pull-off stress as the confinement, i.e., the ratio between substrate diameter and film thickness, increases 38,39 . Based on these results and the data depicted in Figure 7, we conclude that composite films with a total thickness of approx.…”
