Most published literature analyzed the elastic modulus of silica aerogels by drawing inspiration from the cellular solids models. For example, Ashby and Gibson (Cellular solids—structure and properties. Cambridge University Press, Cambridge, 1997) describe the open cellular foam model compressive modulus to follow power law dependence on the relative density as shown in Eq. 5.1 where C and μ are geometric constants that depend on the topological features and microstructure undergoing cell wall bending as the dominant deformation.
