Application of fractional calculus to fractal media

Research output: Chapter in Book/Report/Conference proceedingChapter

Abstract

This chapter is a survey of continuum-type mechanics of porous media having a generally anisotropic fractal geometry. The approach relies on expressing the global balance laws in terms of fractional integrals based on product measures and, then, converting them to integer-order integrals in conventional (Euclidean) space. Via localization, this allows development of local balance laws of fractal media: conservation of mass, microinertia, linear momentum, angular momentum, and energy; also the second law of thermodynamics. The product measure formulation, together with the angular momentum balance, directly leads to a generally asymmetric Cauchy stress and, hence, to a micropolar (rather than classical) mechanics of fractal materials. The continuum-thermodynamic development follows the lines of thermomechanics with internal variables.
