From fractal media to continuum mechanics

The paper presents an overview of modeling fractalmedia by continuum mechanics using the methodof dimensional regularization. The basis of thismethod is to express the balance laws for fractalmedia in terms of fractional integrals and, then, con-vert them to integer-order integrals in conventional(Euclidean) space. Following an account of thismethod, the authors develop balance laws of fractalmedia (continuity, linear and angular momenta, en-ergy, and second law) and discuss wave equations inseveral settings.

Symmetry classes for odd-order tensors

The authors give a complete general answer to the problem, recurrent in continuum me-chanics, of determining the number and type of symmetry classes of an odd-order tensorspace. As an illustration of this method, and for the first time, the symmetry classes of allodd-order tensors of Mindlin second strain-gradient elasticity are provided.
