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
