it seems that a material such as this needs multiple trials to have averaged in to record accurate results.

Mom my Candy broke!! @.@

try UHMWPE

[tenshichanyo]

You should do one of Polycarbonate. Thanks

[evanpilot]

can you guys make a vid of you guys testing the tensile strength of Polyethylene terephthalate

The graphs are "engineering stress" and "engineering strain" as stated in the "more info" description. As the prior person commented, engineering stress uses the initial cross sectional area and true stress uses the constantly changing (reducing as it yields) area. It is always more difficult to produce a true stress-strain graph. Engineers mostly use engineering graphs, but true graphs are more useful in manufacturing where lots of plastic deformation is required.

cant be true stress unless it can work out the new cross sectional area lol

[Hwatmos]

is it a engineering or true stress strain graph?
