Finite strain analyses of deformations in polymer specimens

Research output: Chapter in Book/Report/Conference proceedingArticle in proceedingsResearchpeer-review

Abstract

Analyses of the stress and strain state in test specimens or structural components made of polymer are discussed. This includes the Izod impact test, based on full 3D transient analyses. Also a long thin polymer tube under internal pressure has been studied, where instabilities develop, such as bulging or necking. An axisymmetric bulge develops on the tube followed by necking in the bulge, and neck propagation is observed in both the circumferential and the axial directions. Analyses of indentation tests have been carried out, with focus on the effect of the material parameters characterizing viscoplastic flow on the indentation response. Also, the ability of the simpler expanding spherical cavity model to reproduce the trends from the 3D finite element solutions has been assessed.
