Example tension stress-strain data. This data was generated by tracing the stress-strain graph for PA12 from the manuscript referenced below. The non-linearity seen at low strain in the original data set was removed, then the data was re-sampling to produce more tightly spaced strain values. Normally-distributed error was added to the stress. The code used to generate the data set can be found at https://github.com/cmstatr/cmstatrExt/blob/master/data-raw/pa12-tension.R
