Edge effects in thin film delamination
WebJul 7, 2013 · Progressive delamination driven by Li-ion diffusion in elastic disk-like thin film electrodes of Li-ion batteries is modeled based on the cohesive model. Axisymmetric diffusion model is considered under both galvanostatic and potentiostatic operations. The effect of edge diffusion on the delamination process is evaluated. It is found that the … WebApr 11, 2024 · The average value of delamination area for PR-1 was around 5072 mm 2, and the delamination reached one side edge of the specimens. The average value of delamination area for PR-2 was around 3695 mm 2. In summary, the delamination area in specimens with the same impact energy was sorted from large to small as RP-1, RP-2 …

[16] provides a classification and investigation of the edge effects that occur in thin interphases in the context of elasticity. The case described in this paper is, essentially, the nonlinear problem of heat transfer in composites with thin layers that are ... WebMar 5, 2024 · In addition to anisotropy issues in textured thin films, another possible cause for deviation from the linearity of d ψ h k l vs sin 2 ψ plots is the presence of stress gradients along the film thickness, especially …
WebMay 3, 2010 · Since many thin polymer films are subjected to tensile residual stresses, effects of residual stress were introduced by first subjecting the thin film to uniform temperature changes in the FEA model. For example, when β r = 10, Fig. 3 shows a contour plot of the distribution of the residual stresses from the FEA model. It also needs to be ... WebFeb 1, 2002 · The effect of humidity on the delamination of boron nitride thin films on silicon substrates was investigated by measuring changes of the mean compressive stress within the films, as well as by ...
