In [30], Tanaka and Tani proved in 2003 the local existence for arbitrary initial data and global existence for sufficiently small initial data of a compressible Navier-Stokes flow

We have developed a nonlinear methodology based on the SolvOpt algorithm of Kappel & Kuntsevich (2000) to optimize the coefficients of the Zener viscoelastic model that

The incremental stress and strain constitutive equations are not restricted to isotropic materials and can be used to resolve complex boundary viscoelastic problems without
