The capillary thinning of a polymeric filament is analysed experimentally as well as by means of numerical simulation. The experimental procedure is as follows. Initially a liquid sample is kept between two cylindrical plates. Then the bottom plate is lowered under gravity to yield a given strain. Thereby the sample is stretched into a filament. Provided the filament is sufficiently long, surface tension will induce a thinningof the filament until breakage in finite time.This experiment was originally deviced by Bazilevsky et al. (1990). For the numerical simulations we employ a Lagrangian finite element technique. This method has previously been used in simulations of the transient filament stretching rheometer (Kolte et al., 1997).
