Hi,
I would like to use the strain-dependent permeability in the poroelastic model, but I am afraid that I don’t have all the parameters that have to be defined (in the Poroelastic Holmes-Mow). In our lab we have used the equation k=k_0*e^(-M*epsilon), where k_0 is the permeability in the reference state, M is the exponential strain-dependent coefficient and epsilon is the strain. We have experimentally determined the value for k_0 and M. But as you can see, I have no information about the solid volume fraction or the power–law exponent.
Isn’t there any other way how to use the easier equation (the one we have used) for the strain-dependent permeability than are the models implemented in the Febio so far (Poroelastic Holmes-Mow, Poroelastic Isotropic Spectral Permeability, Poroelastic Transversely Isotropic Spectral Permeability, Poroelastic Orthotropic Spectral Permeability)?
Thanks
Michala
