Abstract
In this study, creep analysis of plain-woven GFRP laminates with an arbitrary phase shift of plain fabrics is performed using the time-dependent homogenization theory developed by the present authors. First, in order to consider an arbitrary phase shift of plain fabrics, a combination of point-symmetric and periodic boundary conditions is employed as a boundary condition for boundary value problems. The time-dependent homogenization theory is then reconstructed by using the boundary condition. Using the present method, in-plane creep behavior of plain-woven glass fiber/epoxy laminates with nine kinds of phase shifts subjected to a constant stress is analyzed.
