| Research Abstract |
In this study, a numerical method for predicting the creep behavior of FRP laminates accurately, was developed using the multi-scale analysis based on the time-dependent homogenization theory. The present method was applied to the analysis of the creep behavior of CFRP laminates at an elevated temperature. The results of analysis agreed with the experimental results, showing the usefulness of the present method. Moreover, the present method was also applied to the creep analysis of plain-woven GFRP laminates. It was shown that the laminate configuration of plain fabrics significantly affected the creep strain of plain-woven GFRP laminates.
