Abstract
<p>In this study, temperature dependence of elastic-viscoplastic behavior of plain-woven glass fiber-reinforced plastic (GFRP) laminates is experimentally observed, and the behavior is analyzed using a triple-scale homogenization analysis method. To this end, tensile tests of a plain-woven glass fiber/epoxy GFRP laminate are conducted under several temperature and strain rate conditions, showing its strong dependence on temperature. Using the experimental results, temperature-dependent elastic-viscoplastic parameters of the epoxy are identified. Using the obtained parameters and the triple-scale homogenization method, elastic-viscoplastic behavior of the plain-woven GFRP laminate is analyzed under several temperature conditions. It is shown that the macro/meso/micro elastic-viscoplastic properties of the plain-woven GFRP laminate significantly depends on the temperature conditions and loading directions. It is also shown that the results of analysis can accurately predict the experimental date in various temperature conditions and loading directions.</p>
