“…Thus, the out-of-phase buckling of the fibers could result in a stabilizing effect, this is in contrast to the postcritical behavior of the in-phase buckling of the fibers. For a detailed analysis of possible bifurcation modes on the micro-scale as well as associated possible macroscopic material instabilities, we refer to Triantafyllidis and Maker (1985), Müller (1987), Abeyaratne and Triantafyllidis (1984), Triantafyllidis and Maker (1985), Geymonat et al (1993), Miehe et al (2002), Aubert et al (2008), and Agoras et al (2009) and the references therein.…”

“…Applying a Bloch-wave ansatz to a fiber-reinforced composite, the authors showed that the onset of a bifurcation on the micro-scale corresponding to the long-wavelength limit (infinite wavelength) leads to a macroscopic material instability. A detailed computational homogenization analysis of structural instabilities on the micro-scale and possible material instabilities on the macro-scale as well as their interactions is performed in Miehe et al (2002), in this context see also Agoras et al (2009) and Aubert et al (2008). A microscopic bifurcation condition of cellular solids, like elastic cellular honeycombs, have been presented in Ohno et al (2002).…”

“…, it is not difficult to show that: along an arbitrary loading path with starting point F = I, the macroscopic stability condition (18) first ceases to hold true at critical deformations cr F with (19) As discussed in Section 6.1 of [5] (see also [25]), the critical condition (19) has a direct physical interpretation. Indeed, the fourth invariant 4 I is a measure of the applied stretch along the fiber direction.…”

“…We begin by solving equation (10) (20) where (21)  1 is a scalar function of the principal invariants 1 I , 4 I , 5 I given by (22) and (23) Here, it is fitting to remark that (20) We are now in a position to utilize the solution (20) in the general equations (5)- On the other hand, the second-order tensor Z introduced in (7) can be shown to specialize to (24) Given (24), it is not difficult to deduce that the eigenvalues of the symmetric secondorder tensor Z T Z defining the Eulerian ellipsoid (6) are given by (25) where (26) are principal transversely isotropic invariants of …”

“…Email addresses: bertoldi@seas.harvard.edu (Katia Bertoldi), pamies@illinois.edu (Oscar Lopez-Pamies) Since 2D idealizations of fiber-reinforced materials -utilized by Rosen [10] and later formalized by Triantafyllidis and Maker [11] in their classical works -are known to lead to results that are qualitatively similar to their 3D counterparts [12,13], here we consider a 2D periodic distribution of long aligned fibers that are bonded to a matrix phase through interphases. Thus we focus on fiber-reinforced elastomers made up of layers of three different materials (r = 1, 2, 3), with volume fractions c…”
