Webwhen these polymers were first cold worked by extruding or drawing. The elastic modulus was in- creased when PC was extruded or drawn while this property exhibited a decrease, due to cold working, for both other polymers. All …
WebSolid polymers—both glass-like and crystalline—can be cold-drawn. In addition to studies of the specific aspects of this process in individual cases, as governed by structural features, the development of a theory of cold-drawing requires an … WebNecking or cold drawing is a smoothed jump in cross-sectional area of long and thin bars (filaments or films) propagating with a constant speed. The necks in polymers, first observed about seventy years ago, are now commonly used in modern processing of polymer films and fibers. Yet till recently there was a lack in
WebJan 11, 2024 · To perform the cold drawing FE simulation I needed an accurate material model that captures the non-linear viscoplastic response of the polycarbonate. In this case I used experimental data for Lexan 9034 from a paper by Mulliken and Boyce [ J. Appl. Mechanics, 2008, Vol. 75 ].
