Abstract:
Inspired by Meyers et al. (Science, 2013), a piecewise model is established so as to individually predict both the heel region and the linear region of stress-strain curve. When the piecewise model satisfactorily predicts the experimental data, the constitutive parameters are precisely identified with definite physical significances. Along with this piecewise guideline, a complete constitutive model can be established for the whole stress-strain curve of collagen fiber tissues with the failure region as well. Graphical abstract.
