This simulation demonstrates "Necking" in a polymer specimen being stretched in a idealised material. A stress/strain curve is generated for an ideal material and a molecular two dimensional "snapshot" is shown of a schematic pair of neighbouring molecules.

Generally, a single polymer sample displays one of the characteristic failure mechanisms under normal conditions, i.e. polystyrene exhibits brittle failure, polyethylene displays necking, crosslinked polydimethylsiloxane displays rubbery behavior, high impact polystyrene displays yielding behavior.

The exact form of the stress-strain curve depends on the polymer under investigation. Indeed not all polymers exhibit necking and cold drawing. Polycarbonate is an example of a brittle polymer...

Free Sculpting Tutorials ... free sculpting tutorial polymer clay ... I must say that I love polymer clay, first (well that’s no news, right?), but I’m very frustrated right now because of one little problem I have with super sculpey, and it is that I can never keep it clean. Has any of you guys got the same issue?
