Schematic representation of the configurations of interest in the CMMI modeling framework. From left to right, ${\kappa }_0^m$ and ${\kappa }_0^c$ represent the cut and stress-free configurations, and ${\kappa }_{tf}^m$ and ${\kappa }_{tf}^c$ represent the uncut and traction-free configurations for the myocytes (superscript m) and the collagen fibers (superscript c), respectively. The uncut, traction-free configuration and the cut, equilibrated configuration of the mixture are represented by ${\kappa }_{tf}^{\ast }$ and ${\kappa }_0^{\ast }$ respectively
