Fig. 11.

Colormaps of strain along the fiber axial ($E11$) and cross-fiber ($E22$) directions for an isolated myocyte within the RTE FE model. (a) Location of the myocyte (cyan) within the undeformed RTE domain, which is connected both to adjacent myofibers as well as the surrounding ECM. Results are shown for maximum applied strain in each of the biaxial modes $E_{11}:E_{22}$ = (b)0.30:0.30, (c) 0.30:0.15, and (d) 0.15:0.30.
