Using finite element model to define how wrinkles form in a single web span without moment transfer
Abstract
This paper describes a finite element model that successfully predicts the formation of troughs and shear wrinkles in plastic webs for a single span bounded by two idler rollers. For this model, wrinkles are created when the down-stream roller is out of tram with the up-stream roller, and there is no moment transfer across the up-stream roller. Variables considered are the span length web width, caliper, and tension.
