A Discrete Probalistic Model of Forces in a Visco-Elastic Thread Pulled Through a Drawing Zone
visco-elastic thread random irregularities tensions probalistic model drawing
2009/2/17
A simulation was carried out of forces acting in a thread of random variable visco-elastic rheological properties, which is displaced through a model drawing zone. This zone consists of two pairs of r...
A Discrete Probability Model of Forces in Yarns Transported Through the Drawing Zone

2009/2/11
A simulation of forces acting in model-yarns transported through the drawing zone was carried out. The model is characterised by two random variables: the length of a yarn segment (link) and the yarn’...
