In this study, the elastic-viscoplastic behavior of plain-woven GFRP laminates in which plain fabrics are stacked with misalignment is analyzed using a homogenization theory. For this, a novel boundary condition for unit cell analysis is proposed based on the periodicity and point-symmetry of internal structures in plain-woven laminates. Using the boundary condition, the homogenization theory for non-linear time-dependent composites developed by the authors is rebuilt for plain-woven laminates with misaligned plain fabrics. As an application of the present theory, the elastic-viscoplastic analysis of plain-woven glass fiber/epoxy laminates with misaligned plain fabrics is performed.
