<p>In the fiber model mechanical anisotropy is adjusted based on an anisotropy measure dependent on stress or strain in such way that the overall elasticity of the material is conserved. The plot shows result of using , and between 0 and 1 in <a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1003410#pcbi.1003410.e084" target="_blank">Equation 7</a>. In our simulations model parameters were chosen such that material anisotropy was close to its maximum when stress anisotropy was about 0.5.</p
