Biological tissues with low porosity
WebQuestion: Biological tissues are deformable. Therefore, the porosity ? depends on the volume dilation, e = (Vf-Vo)/Vo. Assuming that the total volume of cells and extracellular matrix molecules do not change during tissue deformation and that the initial porosity is ?0, derive the relationship between ? and e. WebJan 17, 2024 · The constitutive model for the porosity-permeability relationship is a powerful tool to estimate and design the transport properties of porous materials, and has thus attracted a significant number of attention for the advancement of composite materials. However, in comparison with engineering composite materials, biomaterials, especially …
