If your simulation doesn't perfectly converge (and I doubt it does, unless you're using hundreds of substeps/iterations), the result will always be larger than 1 under even the slightest external force/acceleration. A simple rope hanging under the force of gravity will have strain > 1.
What you probably want is to compare the strain to a threshold (eg 1.1, 1.2, etc). If the strain is over this threshold, then you consider the rope as "stretched".
