Abstract

In this paper, the particle model of concrete developed by Jirasek & Bazant is applied to mortar and concrete specimens to analyze a correlation between microscopic and macroscopic fracture nature. First, the particle model of three-component material is formulated and microscopic .·mortar parameters are determined by some numerical identification. Next, concrete prisms and notched beam specimens having each differing parameters are analyzed. Numerical examples show good agreement with test results and also explain an effect of aggregate size used. Finally, fracture simulation of concrete under compression is conducted to show a limitation of the present particle model.
