Abstract

The 3D Lagrangian integral method is used to simulate the effects of the rheology on the viscoelastic end-plate instability, occuring in the rapid extension of some polymeric filaments between parallel plates.It is shown that strain hardening materials with a negative second normal stress difference undergo the instability at a highter critical Hencky strain compared to materials with zero second normal stress difference. Furthermore it is demonstrated that strain hardening in itself playes a key role in the development of the instability in polymeric materials.
