DOI: 10.1007/s00161-017-0595-5
Abstract: There are, in each branch of science, statements which, expressed in ambiguous or even incorrect but seemingly friendly manner, were repeated for a long time and eventually became diffusely accepted. Objectivity of physical fields and… read more here.

DOI: 10.1016/j.ast.2021.106591
Abstract: Abstract As all known, there exists extremely thermal and chemical non-equilibrium phenomenon in hypersonic flows. Much effort has been put into the development of computational models for the prediction of such non-equilibrium flow. In order… read more here.

DOI: 10.1016/j.ijnonlinmec.2020.103526
Abstract: Abstract A constitutive relation is proposed for viscoelastic bodies that is a generalization of the classic Kelvin-Voigt model, wherein the left Cauchy Green tensor, the symmetric part of the velocity gradient, and the Cauchy stress… read more here.

DOI: 10.1016/j.mechrescom.2017.11.002
Abstract: Abstract Initial stresses originate in soft materials by the occurrence of misfits in the undeformed microstructure. Since the reference configuration is not stress-free, the effects of initial stresses on the hyperelastic behavior must be constitutively… read more here.

DOI: 10.1103/physrevlett.128.071601
Abstract: We investigate the effects of nonlinear stochastic interactions on hydrodynamic response functions. The interactions are parametrized by "stochastic transport coefficients" that are invisible in the classical constitutive relations, but nonetheless affect the late time hydrodynamic… read more here.
