Notes:
In the present study, a method for reducing the domain of analysis is developed for thehomogenization analysis of plain-woven laminates. Moreover, the method is applied to thequantitative prediction of elastic-viscoplastic deformation of plain-woven GFRP laminates. It is firstshown that the internal structures of plain-woven laminates satisfy point-symmetry on the assumptionthat the laminates have the in-phase or out-of-phase laminate configuration of plain fabrics. Thepoint-symmetry is then utilized for the boundary condition of unit cell problems, reducing the domainof analysis to 1/4 and 1/8 for the in-phase and out-of-phase laminate configurations, respectively.Using the present method combined with the nonlinear time-dependent homogenization theory, theelastic-viscoplastic behavior of plain-woven GFRP laminates under in-plane on- and off-axis loadingis analyzed. In addition, the tensile tests of a plain-woven GFRP laminate at a constant strain rate areperformed at a room temperature. Comparing the results of the present analysis with the experimentalones, it is shown that the analysis successfully predicts the in-plane elastic-viscoplastic behavior ofthe plain-woven GFRP laminate
