積層Mindlin板要素を用いた均質化法による道路舗装体の有限要素解析

抄録

This paper presents a multi-scale finite element method for the analysis of pavement structure based on homogenization method and layered Mindlin element. The homogenization method is employed to consider the effect of mechanical behaviors of microscopic structures of pavement. The composite plate theory is also introduced to obtain a homogenized elastic tensor. The present method is applied to two numerical examples; 2-layer plate analysis and FWD (falling weight deflector) test analysis, and the computed results are compared with theoretical, experimental and 3-D computational results. The method is shown to be a useful method for the large-scale analysis of pavement structures.
