"The paper offers a critical comparison between the finite element (FE) simulations exploiting the unit cell model and the two-point averaging scheme derived from the application of the Hashin-Shtrikman variational principles to nonlinear viscoelastic random fibrous composites. The presented results suggest that in attempt to reduce the computational cost, e.g., with the help of two-point averaging scheme, a caution must be exercised particularly in applications that include localization of inelastic deformation in one of the phases." . .
