Situations of contact between deformable bodies are very common in industry and everyday life such as train wheels with the rails, a shoe with the floor, tectonic plates, the car’s braking system, etc. Because of the importance of the contact problems, a considerable effort has been made in the modeling and numerical simulations, and the engineering literature concerning this topic is rather ex...

Recently much of the research has been dedicated to the application of fractional calculus in rheology. In this paper fractional-order spectra are presented for the complex viscoelastic materials, which mechanical analogy are constructed by fractional elements connected in series or parallel. Fractional-order spectra connect directly to the material’s constitutive relation with fractional deriv...

Chiral materials are not invariant to inversions: there is a distinction between rightand left-handed material. Material properties such as piezoelectricity and pyroelectricity, represented by tensors of odd rank, can only occur in chiral materials. Chiral e!ects in elasticity cannot be expressed within classical elasticity since the modulus tensor, which is fourth rank, is unchanged under an i...
