Analysis of the creep behavior of thin polymer films by finite elements simulation of micro-bubble inflation
Abstract
Finite elements simulations have been performed to investigate the various effects bound to influence the viscoelastic response of nano-confined polystyrene films, among which surface tension, residual stresses, properties gradient. The work is based on the micro-bubble inflation experiment developed by McKenna et al. [1,2]. The preliminary results presented here focus on the analysis of the stress gradients into the film, the influence of the boundary conditions and some aspects of the film preparation.
