425 イメージベース有限要素法によるコンクリート材料の非線形解析

抄録

We have been developing an image-based 3-D finite element procedure for simulating the mechanical behaviors of concrete materials subjected to compression. On the assumption that concrete materials consist of coarse aggregates and mortar, the digital image captured from a physical concrete specimen is directly used as a finite element mesh. In this modeling, tensile failures on interface on interface between coarse aggregate and mortar are considered.
