Abstract

A fully three-dimensional rate and temperature dependent finite strain plas- ticity model for semicrystalline nylon 6/6, originally developed for finite in- elastic deformation in metals [2],[4], has been implemented in the explicit, Lagrangian finite element code DYNA3D [16]. The model has been previ- ously implemented into the implicit code NIKE2D [10] for comparing the engagement process of nylon obturators relative to that of copper obturators [14]. The DYNA3D material driver was used to verify model implementa- tion for constant strain rate input histories by comparing true stress versus true strain results with predictions from Bammann's closed-form model and NIKE2D implicit finite element results. The material model is being used for modeling the interaction a
