Abstract

Cardiac tissue is probably best characterized as a solid-fluid mixture exhibiting nonlinearly anisotropic, regionally heterogeneous, and perhaps incompressible behavior. To gain additional insight into the basic mechanics of indentation experiments on cardiac tissue, the authors studied a related analytical problem. In the paper, they present graphical predictions for Mooney-Rivling and exponential materials subjected to finite in-plane equibiaxial extensions and small superimposed indentations by a rigid punch. The authors' findings are qualitatively similar to the experimental data on cardiac tissue, and they discuss potential implications to cardiac mechanics.
